{"version":"1.0","type":"rich","title":"Bar Chart Sequential Scale","description":"This bar chart visualizes the wealth of billionaires, using a sequential color scale where bar fill intensity corresponds to net worth in billions. The chart encodes value through both bar height and color, with a legend explaining the color mapping. Built with D3 v6, it loads CSV data, applies a linear color scale from white to blue, and renders SVG rectangles. The visualization uses `d3.scaleBand` for x-axis positioning and `d3.axisBottom` for ticks. A `d3.legendColor` legend clarifies the color scale. Hovering highlights each bar in red, and tooltips display exact values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b4da4604719947cc8ce10a5fc75e4801?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
