{"version":"1.0","type":"rich","title":"bar chart-5320","description":"This bar chart displays the distribution of speed limits across different road types, with each road type represented by a vertical bar and its corresponding average speed limit. The visualization is built using D3.js v7, rendering to an SVG canvas. The chart loads CSV data from a GitHub Gist, then uses `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis. Bars are drawn as `rect` elements, with x-axis labels rotated diagonally for readability. The color of each bar is a consistent teal, and the chart includes margins and axis labels for clarity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f69532e83f5481abce5abd836f2edf7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
