# What's New

This section is for users who are using the previous version of FusionCharts in their application. Here we'll talk about the new features introduced in v3.15.0.

It's been a while since we introduced a new chart. So this time around, we thought why not surprise you and bring in three new charts, highly requested by you, that aid in visualizing newer forms of data.

## Sunburst Chart

A Sunburst chart is used to visualize relationships within hierarchical data. It shows hierarchy through a series of concentric rings, where each ring corresponds to a level in the hierarchy. Each ring can have multiple segments; each segment showing the contribution of a particular dimension in that hierarchy. Focussing on a segment in the ring gives a sense of the part to the whole relationship of this dimension with respect to its parent ring segment.

A Sunburst chart shares similarities with a Ring Chart, Multi-level Pie Chart, Belt Chart, and a Radial Treemap.

A Sunburst chart looks as follows:

## Sankey Diagram

Sankey Diagram is a type of flow diagram that depicts the flow of resources (material, energy, cost, etc.) from one node to another. A Sankey Diagram can be drawn in either a horizontal layout (default) or a vertical layout. A Sankey Diagram with horizontal orientation looks as shown below:

There are 19 nodes in the Sankey Diagram provided above. A link connects any two nodes that are related to one another (i.e, a flow happens between them). If you hover over a node, you will see all the links (or relationships) associated with it. Hovering on a link will show all nodes associated with it.

## Chord Diagram

A chord diagram is a graphical way to represent flow relationship between specific entities in transitioning data. The entities (called nodes) are drawn along the circumference of a circular layout. The flow relationships (called links) are represented by arcs that connect the nodes.

Chord Diagrams are also referred to as Radial Network Diagram, Chord Layout, or Dependency Wheel.

A simple Chord Diagram looks as shown below:

In the above diagram, there are `n` nodes. A link connects a pair of nodes where a relationship exists. Hovering on a node shows all the links (or relationships) associated with it. Likewise, hovering on a link shows the related nodes.

## New Functionalities in Box and Whisker Chart

A box and whisker chart is a statistical chart that is used to examine and summarize a range of data values. Starting v3.15.0, FusionCharts Suite XT has introduced the following features in the existing box and whisker chart:

• Scrolling feature has now been enabled in the box and whiser chart.

• You can apply a custom color to the icon borders. You can use `numVisiblePlot` attribute to control the number of plot points visible on the chart canvas.

• Box and whisker chart can now be used in two different ways:

• Provide values and expect the chart to determine the summarised values.
• Provide summarised values to a box and whisker plot.
• Five new attributes have been introduced to explicitly set the data values of the mean, MD, SD, QD and outlier.

• `showMeanValue`

• `showMDValue`

• `showSDValue`

• `showQDValue`

• `showOutlierValue`

• New attributes have been introduced to set the position of the values for mean, MD, SD, QD and outlier.

• `meanValuePosition`

• `MDValuePosition`

• `SDValuePosition`

• `QDValuePosition`

• `outlierValuePosition`

• You can now add custom color to the border of the icons of mean, MD, SD, QD and outlier.

• `meanIconBorderColor`

• `MDIconBorderColor`

• `SDIconBorderColor`

• `QDIconBorderColor`

• `outlierIconBorderColor`
