You know the market map from Finviz, tiles sized by market cap and colored by the day's move. It's now a component you can render on demand.
colorMode: "change" is the market-heatmap look. Tiles are sized by value and colored on a diverging red-to-green scale from each tile's change %, from neutral at 0 to full color at maxChange.
colorMode: "category" is a weighted breakdown (budget, storage, traffic mix) colored by a palette or a per-tile color.
Add a group to each tile and they nest into labeled sector bands, market-map style. The layout is a proper squarified treemap, so tiles stay close to square and stay readable.
