Who doesn't love sunbursts? Visit my blog for more. In this page, we'll do a detailed walk-through of a basic "no frills" d3 Sunburst. We'll add features in future tutorials. I strive to explain each line. If I don't explain it, or explain it well, I welcome your input. For each titled section, we'll begin with the code and then explain it. Maybe it'll help you solve a problem in your own code or build something that you're proud of. On the bl. Part 2 builds on this tutorial, but adds labels and pulls the data from a separate json file.

Sunbursts are great for explaining relationships in hierarchical data. But the code can get confusing as we mix html, css, svg, json, javascript, and d3. And, bounce between radians and degrees. This is where our d3 visualization will actually get drawn. JSON for a sunburst is structured as a hierarchy. This JSON contains data about 11 nodes. We'll call these arcs when we calculate each node's size in d3 code. And we sometimes call them slices when we're looking at our visualization.

The root node is a sort of anchor for our data and visualization, and we often treat it differently since it's the center of or sunburst. We define each node in the above data in 1 of 2 ways:. Size isn't defined for these nodes, because it'll be adopted calculated by d3 based on children nodes. Children will either be more nodes like this one, with children of their own, or nodes with a "size" when it has no children.

The hierarchy does not need to be symmetrical in any way if. Nodes can have differing numbers of children, or have "sibling" nodes that have no children at all. But we'll use this values a few times. If we coded it directly, we'd then need to change each occurrences every time. Mistakes will happen. Then we store that value as our radius.Starting basic: you have an element and want to color it. You have several way to provide this color:. You have a several groups, and want to attribute a specific color to each group.

Several way to build this scale. Just calling a color Starting basic: you have an element and want to color it. You have several way to provide this color: Hex code, like 69a3b2. You can use this tool to find the Hexcode you need. Using rgb or rgba : gives the quantity of red, green and blue between 0 and Using the d3-color plugin.

This then allow to apply different type of customization. Sequential color scale You have a numeric variable and want to map it to a color scale. Several way to build this scale Give 2 colors as a range. Use scaleLinear Use a palette coming from ColorBrewer. Use scaleSequential. List of available palette here. These color scale are offered in the d3-scale-chromatic plugin Palette coming from viridis.

Same idea. Categorical color scale You have a several groups, and want to attribute a specific color to each group.

For example the tree layout takes a hierarchical data structure and adds x and y values to each node such that the nodes form a tree-like shape:.

D3 has a number of hierarchy layouts for dealing with hierarchical or tree data as well as a chord layout for network flows and a general purpose force layout physics-based simulation. For example a simple function that adds positional information to an array of data can be considered a layout. Note that treemappack and partition are designed to lay out hierarchies where the nodes have an associated numeric value e.

D3 version 4 requires the hierarchical data to be in the form of a d3. It has a number of functions defined on it for retrieving things like ancestor, descendant and leaf nodes and for computing the path between nodes.

It can be created from a nested JavaScript object such as:. More examples of hierarchy functions. The tree layout arranges the nodes of a hierarchy in a tree like arrangement. We can then call treeLayoutpassing in our hierarchy object root :. In the case of root. The cluster layout is very similar to the tree layout the main difference being all leaf nodes are placed at the same depth.

Treemaps were invented by Ben Shneiderman to visually represent hierarchies where each item has an associated value. For example, we can think of country population data as a hierarchy where the first level represents the region and the next level represents each country.

A treemap will represent each country as a rectangle sized proportionally to the population and group each region together:. Before applying this layout to our hierarchy we must run.

This traverses the tree and sets. Note that we pass an accessor function into. We can now call treemapLayoutpassing in our hierarchy object:. The layout adds 4 properties x0x1y0 and y1 to each node which specify the dimensions of each rectangle in the treemap.

Now we can join our nodes to rect elements and update the xywidth and height properties of each rect :.

In the example above paddingTop is 20 and paddingInner is 2. Treemaps can use different tiling strategies and D3 has several built in treemapBinarytreemapDicetreemapSlicetreemapSliceDicetreemapSquarify and the configuration function.

The effect of different squarify ratios can be seen here. The pack layout is similar to the tree layout but circles instead of rectangles are used to represent nodes. In the example below each country is represented by a circle sized according to population and the countries are grouped by region. As with the treemap we must call.

The pack layout adds xy and r for radius properties to each node. Now we can add circle elements for each descendant of root :. Labels can be added by creating g elements for each descendant:. The padding around each circle can be configured using. The partition layout subdivides a rectangular space into a layer for each layer of the hierarchy. Each layer is subdivided for each node in the layer:.Interactive visualizations can add an impressive oomph to plain and boring datasets.

The main characteristic of interactive data is in its use as an application on its own. It allows users to select specific data points to visualize the story in the way they choose. One of the most powerful ways to accomplish this is through JavaScriptor more specifically, the D3. In the above example, mousing over specific points of data launches a pop-up that expresses more information on that particular piece of data.

The graph itself can be further animated, creating an exciting view of user data. See it in action here. Clicking anywhere on this coffee flavour wheel causes it to zoom with one fluid, dynamic motion. Check it out here. If you really want to dive into the technical details, this is an example of using a d3.

A sunburst tree is a special radial space-filling visualization which is similar to an icicle tree. All in all, D3 allows users to create basically any type of visualization, purely based on data, rather than from personal understanding of the data.

Whether it be a table or a pie chart, a graph or a bar chart, D3 avoids human error by streamlining the process of data visualization, while giving users every opportunity to make tweaks and control visualization features. These animations are also fast and responsive to user interactions, making them even more appealing. The very first step of D3 is to set up the D3 library, which functions as a repository of information and instructions for the D3 code to draw from.

There are two ways to do this:. These are very similar to existing conventions, and are therefore easy to use from a coding perspective. You can add animations and other features in a similar fashion, using different scripts that can be found in the API reference on the official website.

The technique of chaining in D3 is done by placing methods together using a period. In this way, outputs of the first method are passed as inputs to the next, simplifying the code.

With its data-driven focus, D3 can easily create candlestick diagrams such as this. The next step is loading your data sets and binding them to your DOM elements.

D3 can handle different types of files, local and external. With data successfully loaded into D3, users can create the most important part of their data visualization: the visualization itself.

This can come in the form of SVGs, which allow your charts to display different shapes, from lines to circles to ellipses, and allow you to have full control to achieve the ideal visualization of your data.

By taking these steps, users are easily able to create the images and shapes that help build full charts and graphs. Instead, the manipulation of geometry and styles through D3 is required to achieve the desired outcome.

This also involves anything from the scale of the chart to its axes to the animations of the chart. However, once you have a grasp of D3. The above diagram displays U. When first opened, the diagram moves according to the timeline, from to Clicking on any part of the timeline causes the diagram to shift accordingly, displaying the trade deficit at that specific period of time.

Take a closer look here.D3 creates a function myScale which accepts input between 0 and 10 the domain and maps it to output between 0 and the range. We can use myScale to calculate positions based on the data:. Scales are mainly used for transforming data values to visual variables such as position, length and colour. Now myScale is a function that accepts input between 0 and and linearly maps it to between 0 and D3 has around 12 different scale types scaleLinear, scalePow, scaleQuantise, scaleOrdinal etc.

In this section we cover scale functions that map from a continuous input domain to a continuous output range.

Linear scales are probably the most commonly used scale type as they are the most suitable scale for transforming data values into positions and lengths. Typical uses are to transform data values into positions and lengths, so when creating bar charts, line charts as well as many other chart types they are the scale to use.

This can be useful for visualisations such as choropleth maps, but also consider scaleQuantizescaleQuantile and scaleThreshold. The exponent k is set using. An interpolator is a function that accepts input between 0 and 1 and outputs an interpolated value between two numbers, colours, strings etc. D3 provides a number of preset interpolators including many colour ones.

For example we can use d3. By default scaleLinearscalePowscaleSqrtscaleLogscaleTime and scaleSequential allow input outside the domain. For example:. If the domain has been computed automatically from real data e. Therefore D3 provides a function. Note that. The domain and range of scaleLinearscalePowscaleSqrtscaleLog and scaleTime usually consists of two values, but if we provide 3 or more values the scale function is subdivided into multiple segments:.

Typically multiple segments are used for distinguishing between negative and positive values such as in the example above. We can use as many segments as we like as long as the domain and range are of the same length. The domain is defined by an array of numbers :. The sorted domain array is divided into n equal sized groups where n is the number of range values.

The split points of the domain can be accessed using. If the range contains 4 values quantileScale computes the quartiles of the data. In the following example we split the domain at 050 and The domain array specifies the possible input values and the range array the output values. D3 can also provide preset colour schemes from ColorBrewer :. When creating bar charts scaleBand helps to determine the geometry of the bars, taking into account padding between each bar.

The domain is specified as an array of values one value for each band and the range as the minimum and maximum extents of the bands e. In effect scaleBand will split the range into n bands where n is the number of values in the domain array and compute the positions and widths of the bands taking into account any specified padding.

The width of each band can be accessed using.NOTE: this block is d3 version 3. Go here instead if you want a version of this block that works with d3 v4, and see the Observable version for d3 v5. This example shows how it is possible to use a D3 sunburst visualization partition layout with data that describes sequences of events. The visualization makes it easy to understand visits that start directly on a product page e.

Where a funnel lets you understand a single pre-selected path, this allows you to see all possible paths.

Non-alphanumeric characters will probably cause problems I haven't tested this. The purpose of the "end" marker is to distinguish a true end point e. For example, include "home-search-end" and "home-search-product-end" but not "home-search" - the latter is computed by the partition layout, by adding up the counts of all the sequences with that prefix. Larger numbers of either of these will lead to a very large CSV that will be slow to process and therefore require pre-processing into hierarchical JSON.

Use templating and data-binding provided by Angular instead. Relying on direct DOM access creates tight coupling between your application and rendering layers which will make it impossible to separate the two and deploy your application into a web worker. So basically you have to use whatever your library is, get the raw element and pass it to Renderer. My recommendation though is to stick to use what angular2 provides you to do this easily without depending on another libraries.

Here's a plnkr with all the cases I mentioned in this answer. Your requirements may differ, of course, but try to use angular2 whenever you can.
