{"version":"1.0","type":"rich","title":"D3 Sequential Color Bar Chart","description":"This bar chart displays natural gas consumption by the electric power sector across eleven U.S. states, with each bar’s length encoding the consumption value in billion BTU. A sequential color scale using `d3.scaleSequential` and `d3.interpolatePuRd` maps higher consumption to darker hues, with a `d3.legendColor` legend clarifying the gradient. The chart is rendered as SVG using D3 v7, with axes created via `d3.axisBottom` and `d3.axisLeft`, and data loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/edcb6894ec8d45e9b1517f496b9ade03?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
