{"version":"1.0","type":"rich","title":"bar chart","description":"This bar chart aggregates student records from a CSV file to display the average math score for each academic department. The visualization uses D3.js v7 with SVG rendering, grouping data via `d3.group` and computing means with `d3.mean`. Bars are positioned using a `scaleBand` for the categorical x-axis and a `scaleLinear` for the y-axis, with axes generated by `d3.axisBottom` and `d3.axisLeft`. Hovering over a bar changes its fill color from blue to orange.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d80c88b8dfb4479b2bd864653b7bd70?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
