{"version":"1.0","type":"rich","title":"Heatmap with tooltip","description":"This example shows a 10x10 heatmap with a custom tooltip that reveals the exact value of each cell on hover. The data is loaded from a CSV file and rendered as colored squares, with a linear color scale mapping values from white to teal. Built with D3 version 6, the visualization uses `d3.scaleBand` for axes, `d3.scaleLinear` for the color encoding, and event listeners for mouse interactions. The tooltip is a styled HTML div appended to the page, positioned using the event’s coordinates and updated on mousemove.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8609c0566a7f44968dba956a334db872?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
