{"version":"1.0","type":"rich","title":"Old Faithful HeatMap","description":"This interactive heatmap visualizes the Old Faithful dataset, showing the relationship between eruption duration and waiting time through a binned 2D grid colored by observation count. The chart updates continuously as the mouse moves horizontally, adjusting the maximum number of bins based on the cursor position. Built with Vega-Lite and embedded via `vegaEmbed`, it uses the `rect` mark with binned quantitative encodings for both axes and an aggregated count color encoding with a greens scheme. Data loads from a TSV file using `d3.tsv` from D3 v4.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a598b48a7ec47ee838ee3adc90f12dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
