{"version":"1.0","type":"rich","title":"Bar chart assignment","description":"This example shows a bar chart of average monthly sales across multiple years, with months from January through December on the x-axis and sales amounts on the y-axis. The visualization uses D3 v7 to load data from a CSV file via `d3.csv`, then binds the data to SVG rectangles using `data().enter().append(\"rect\")`. It employs `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis, with axes rendered by `d3.axisBottom` and `d3.axisLeft`. The bars are filled with a steelblue color, and the chart includes a titled heading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/982b6608d3f14f6fad52b425fbeddaf7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
