{"version":"1.0","type":"rich","title":"Old Faithful HeatMap 08","description":"This example visualizes the Old Faithful dataset as a 2D heatmap, splitting the data into four facet panels based on two repeated row and column fields. Each panel displays binned counts of eruptions, with color intensity representing frequency, using a green color scheme. The visualization is built with Vega-Lite and Vega-Embed, leveraging the `repeat` operator and a `Maxbins` parameter bound to a slider for interactive bin-width control. Data is loaded from a CSV via D3’s `d3.csv`, and the chart renders as SVG with a transparent view stroke.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ed891aef82c64abab5c898ec5b6e347c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
