This visualization displays a grid of company squares, each colored by a relevance score using a linear color scale from light gray to dark teal. The heatmap uses D3 v7 to render SVG rectangles and text labels for company symbols and scores. Data is loaded as JSON from a GitHub gist, and interactive tooltips show company details like industry and description on mouseover. A color legend along the bottom maps the VectorScore range from 0 to 10.
