Meet FusionCharts 3.15: Chord, Sankey, Sunburst Charts & More

FusionCharts 3.15, which was recently released, adds three new data chart types, as well as other improvements and updated documentation. More information can be found in the changelog.

Read on about the new data chart types in FusionCharts 3.15

as well as some interesting and well-explained examples! Let’s get started!

Chord Diagram

A chord diagram is an interesting way to represent weighted relationships or dependencies in a radial layout. Elements (or nodes) amongst which the weighted relationship exist are drawn on the circumference, whereas the actual weighted relationship is drawn as links in the circular space of the chord diagram.

In addition to visualizing relationships, the magnitude of each connection is also shown as a flow or movement. For example, the migration of people from one country to another, or the subscribers switching telecom operators. The essence of a chord diagram is in knowing which is the dominant relationship and one can toggle to narrow focus on the most important relationships. It can be used to show comparisons and relationships.

Sankey Diagram

The Sankey diagram is very helpful to represent the flow in a system. The flow happens between relatable entities and is represented by colored links. Also, the flow could be of any measurable quantity – material, cost, energy, etc, from one node (or entity) to another. It can be drawn in different layouts and gives a quick understanding of the flow balance in the system. You can use it to depict the energy flow in a system, or resource flow among members, or import/export among countries, etc.

A Sankey diagram puts a visual emphasis on the major transfers or flows within a system to help capture attention on the most important flow. They also help locate dominant contributions to an overall flow. The primary function of the Sankey diagram is to represent flow, process, and proportions.

Sunburst Chart

The Sunburst chart can be used to visualize relationships within hierarchical data. It shows the hierarchy through a series of concentric rings, where each ring corresponds to a level in the hierarchy. Each ring can have multiple segments, with each segment showing the contribution of a particular dimension in that hierarchy.

Focusing on a segment in the ring gives a sense of the part to the whole relationship of this dimension to its parent ring segment.

Furthermore, the Sunburst chart is the most effective in showing how one ring is broken into its contributing pieces (i.e, sequential segments). Any data with a rich categorization on any measurable quantity can be easily visualized using a Sunburst chart. It can be used to represent the hierarchy in data and for part-to-a-whole analysis.
