What is the purpose of sunburst?

The sunburst chart is ideal for displaying hierarchical data. Each level of the hierarchy is represented by one ring or circle with the innermost circle as the top of the hierarchy. A sunburst chart without any hierarchical data (one level of categories), looks similar to a doughnut chart.

What is sunburst visualization?

The SunBurst technique is an alternative, space-filling visualization that uses a radial rather than a rectangular layout. In SunBurst, items in a hierarchy are laid out radially, with the top of the hierarchy at the center and deeper levels farther away from the center.

What is Treemap good for?

Tree Maps are primarily used to display data that is grouped and nested in a hierarchical (or tree-based) structure. Example: There are approx 10-15 major categories of cause of death – Circulatory System Diseases, Cancers, Respiratory Diseases, External Causes of Mortality etc.

Why sunburst Visualisation is more effective for hierarchical plots?

It presents the entire hierarchical data in a single-screen snapshot, which makes it a preferred choice over a tree view. Sunburst charts shows the hierarchy of the categories, thereby giving a very clear understanding of the lineage.

What is the sunburst effect?

A sunburst is frequently used in emblems and military decorations. Sunbursts can appear in photographs when taking a picture of the Sun through the diaphragm of a lens set to a narrow aperture due to diffraction; the effect is often called a sunstar.

What is a sunburst plot?

Sunburst plots visualize hierarchical data spanning outwards radially from root to leaves. Similar to Icicle charts and Treemaps, the hierarchy is defined by labels ( names for px. icicle ) and parents attributes. The root starts from the center and children are added to the outer rings.

What is a sunburst pie chart?

Sunburst Chart — also known as Ring Chart, Multi-level Pie Chart, and Radial Treemap — is typically used to visualize hierarchical data structures. A Sunburst Chart consists of an inner circle surrounded by rings of deeper hierarchy levels.

When should you not use treemap?

Limitations of a treemap chart

You cannot display data that varies in magnitude.
Out of the two quantitative variables that a rectangle represents, the variable standing for the size of the rectangle cannot have a negative value.

How does a treemap chart work?

A treemap chart provides a hierarchical view of your data and makes it easy to spot patterns, such as which items are a store’s best sellers. The tree branches are represented by rectangles and each sub-branch is shown as a smaller rectangle.

What is the purpose of waterfall chart?

Waterfall Charts are used to visually illustrate how a starting value of something (say, a beginning monthly balance in a checking account) becomes a final value (such as the balance in the account at the end of the month) through a series of intermediate additions (deposits, transfers in) and subtractions (checks …

How do you get the sunburst effect?

Partially blocking the sun with objects, such as a mountain peak or branches or a hand with the “ok” sign, will make the sunburst much more pronounced. The effect is increased because by slightly impeding the passage of light, the diffraction of the light is increased before it hits your aperture.
