{"version":"1.0","type":"rich","title":"Bar Graph Vizualization","description":"This bar chart visualizes the distribution of CSS levels across a dataset of colors, showing how many colors correspond to each specification level. The chart uses a vertical bar layout with hover effects that change bar color from steelblue to orange. Built with D3 v7, the visualization loads CSV data from a GitHub gist, aggregates counts with `d3.rollup`, and renders the chart as an SVG using `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. Axis labels and rotated x-axis tick text clarify the categorical and numeric values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa299caa97c84c6cac5defd990f6b4ec?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
