A treemap is a technique for visualizing hierarchical data by using rectangles nested within each other. Treemap charts are created using this technique for data visualization.
Treemap charts represent hierarchical data as tree structures. Data are represented as branches and subbranches by rectangles, whose dimensions and colors are determined by the quantitative variables associated with each rectangle: each rectangle represents two numerical values. Data can be drilled down to, in theory, an unlimited number of levels. This makes it easy to distinguish at a glance between categories and data values.
In Retool you can, for sure, create a treemap chart using the build-in Plotly component using (and messing with) a custom JSON configuration.
Here a simple treemap configured visually using our configurator (a Retool app):
Here a list of what you can configure in this current treemap implementation:
