{"version":"1.0","type":"rich","title":"Old Faithful HeatMap A","description":"This interactive heat map visualizes the Old Faithful geyser dataset, showing the relationship between eruption duration and waiting time through a grid of colored rectangles. Using Vega-Lite’s binned aggregation, each cell’s color encodes the mean waiting time for eruptions within that bin, with a greyscale heatmap color scheme. The visualization is rendered as SVG via `vegaEmbed`, with the bin count dynamically adjusted based on mouse X position, triggering a re-render through the `d3.select` mousemove handler. Data is loaded from a TSV file using `d3.tsv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/727b7c8ab4064937accb697878f7c1d1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
