Scores are rounded to the nearest 0.3 unit using a custom rounding function, and a 10-step color legend is rendered beneath the grid. Built with D3 v7, the visualization reads JSON data from a GitHub gist, uses SVG rectangles and text for rendering, and includes interactive tooltips on mouseover that show company details alongside a fixed information panel.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd05fef21b3d40ed948bc93f8256f15e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
