This gallery example visualizes five fundamental color-scale patterns—sequential, diverging, categorical, highlight, and alert—through a grid of annotated mini bar charts. Each pattern shows how color encodes quantitative or categorical data, using palettes like blues for sequential, diverging browns and greens, and gray tints with accent colors for highlighting. The D3 v7 code uses `scaleLinear` and `scaleBand` to compute bar heights, while custom wrapping logic measures text via `getComputedTextLength`. The layout is fixed with responsive container sizing, and the visualization is based on concepts from "The Big Book of Dashboards."
