A grid of colored cells shows relative scores for a set of financial symbols from a JSON dataset, with each cell labeled by its ticker symbol and score. A linear color scale maps scores from red to green, and a gradient legend below the grid indicates the mapping. The visualization renders as SVG using d3.v7, with mouseover interactions defined but not detailed, and a tick indicator labeled "HI" marks a reference point. Data is loaded via `d3.json`, and scales are created with `d3.scaleLinear`.
