{"version":"1.0","type":"rich","title":"Fork of API Heatmap - brand colors round  20 steps","description":"This example uses a linked dataset of company descriptions and relative scores to create a 20-step heatmap grid. Rendering as a flexible HTML/CSS grid, each of the 20 cells is colored by a three-color gradient from light gray to dark teal, based on the company's relative score rounded to the nearest half. The visualization includes interactive tooltips, a mouse-following indicator, and a details panel that appears on click, showing company information like industry and a link to its Nasdaq page. The chart uses D3's `scaleLinear` for color mapping and `json()` for data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3d60ab8d3dcb45faae804fc07c377f47?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
