{"version":"1.0","type":"rich","title":"Old Faithful HeatMap","description":"This example visualizes the Old Faithful eruption dataset as a binned 2D heatmap, showing the joint distribution of eruption durations and waiting times through a green color scale. The visualization updates dynamically as the mouse moves across the page, adjusting the number of histogram bins along the x-axis based on the cursor’s horizontal position. Built with Vega-Lite and embedded via vegaEmbed, the chart renders as SVG, while d3.tsv fetches the raw data from a GitHub gist and d3.select listens for mousemove events to re-render the specification.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f08fca1f02247888a7490836921ee57?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
