A Circle Packing Chart displays hierarchical data as nested circles, where each circle represents a node and its size reflects the underlying value. It is a visually compelling alternative to treemaps for exploring multi-level categorical structures.
This sample maps ancient Greek philosophers into a hierarchy of schools and lineages, loaded from JSON. A dark-blue theme colors nodes by depth using the active palette, hover states progressively darken circles, and labels are anchored near the top center for readability.
Follow the step-by-step Circle Packing Tutorial to learn how such charts are built. See the Circle Packing documentation for all configuration options.
