{"version":"1.0","type":"rich","title":"bar grapgh","description":"This bar chart displays total sales across product categories, with each category represented by a colored bar on a band scale. The visualization uses D3.js v7 to load CSV data from a GitHub gist, map it into an array of category-total pairs, and render an SVG chart with axes, labels, and a legend. The code applies a sequential color scheme via `d3.scaleOrdinal` with `d3.schemeCategory10`, and uses `d3.axisBottom` and `d3.axisLeft` for the axes. A title and rotated category labels are included to improve readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5eec99f03bd84d95ab1240806732c35f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
