{"version":"1.0","type":"rich","title":"API Heatmap","description":"A grid of colored squares displays companies, each labeled with its ticker symbol and a numeric \"rel_score.\" A red-to-green linear scale maps these scores, and hovering over a square reveals company details like name, industry, and description in a tooltip and a fixed info panel. The visualization is built with d3.v7, using `scaleLinear` for color mapping, `.join()` for SVG element creation, and mouse event handlers for interactivity. Data comes from a JSON file hosted on a GitHub gist.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8f3a4303817443c1951df8be75472059?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
