Tritium UI
TritiumTreemapView
Size rectangles by value so a hierarchy, or a flat list, is easy to compare.

- Lay out with squarified, slice-and-dice, or strip algorithms, and choose the strip direction.
- Color by category or on a continuous scale from one color to another.
- Drill into a branch, show a breadcrumb, and animate the drill.
- Show labels, compact value text, and tooltips.
- Highlight nodes whose label matches a search string.
- Select a tile and handle ItemTapped and DrillChanged.
- Export the treemap to a PNG stream or file.
