{"version":"1.0","type":"rich","title":"D3 Gallery tooltip example","description":"This example shows a heatmap of the `heatmap_data.csv` dataset, with each cell colored according to its value using the `d3.scaleSequential` interpolator with the Inferno color scheme. Hovering over a cell triggers a tooltip that displays the exact value of that cell, implemented via mouse events and the `d3.select` API. The SVG rendering includes axes built with `d3.axisBottom` and `d3.axisLeft`, and the tooltip's position is set using `d3.mouse`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3ed696456cf7413aba56ac6e81832cb8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
