{"version":"1.0","type":"rich","title":"Old Faithful HeatMap A 02","description":"This visualization displays the Old Faithful dataset as a binned 2D heatmap using Vega-Lite. It shows the relationship between eruption durations and waiting times, with each rectangular bin colored by the mean waiting time. The code builds a layered specification including a rect mark for the heatmap and a text mark for mean values. It uses `vegaEmbed` to render the chart, with `d3.tsv` loading the raw data from a Gist. The bin count is configurable via a `bins` parameter, and the color scheme is set to \"greens\".","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b8ada7092d314a3eaf97714949bce52c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
