{"version":"1.0","type":"rich","title":"Combined chart Assignment","description":"This visualization presents retail sales trends for Electronics, Clothing, and Groceries across 150 months using two SVG charts. The first chart displays three multi-series line graphs with a dashed annotation marking the peak Electronics sales month. The second chart combines a bar chart of total monthly sales with an overlaid line for Electronics revenue. Built with D3 v7, the example loads CSV data, uses `d3.line` and `d3.scaleBand`/`d3.scaleLinear`, and includes gridlines and legends to clarify the dual representations.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f5a1a6871cdb4fa1b21d1e84b85d7aae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
