{"version":"1.0","type":"rich","title":"Fork of Old Faithful HeatMap","description":"This interactive visualization presents the Old Faithful dataset as a 2D heatmap, showing the relationship between eruption durations and waiting times. The plot uses a binned rectangular mark, with color intensity representing the count of observations in each bin, rendered using Vega-Lite’s `bin` encoding and `aggregate: \"count\"`. The code employs a minimal setup with D3.js to fetch the TSV data and re-renders the visualization on every mouse movement, dynamically adjusting the bin count via `Math.round(bins)`. Consequently, the heatmap’s granularity responds directly to the horizontal cursor position, letting viewers explore different binning resolutions. The visualization relies on vega-embed to render the specification as a static SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f07bef36e0fc480fbc9e95b08ca7e7a7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
