CirclePacking
Circle Packing supports the following visual channels:
color: color channel, supportsmultiple dimensionsor one measure
label: label channel, supportsmultiple dimensions and multiple measures
tooltip: tooltip channel, supportsmultiple dimensions and multiple measures
Circle Packing, used for displaying hierarchical data, representing numerical values through circle sizes.
Applicable scenarios:
- Displays the proportion distribution of hierarchical data
- Emphasizes containment relationships in data
Data requirements:
- At least 1 numeric field used to map the size of circles
- At least 1 dimension field used for hierarchical partitioning
