multi charts
✓ Published2🌍 Public
This example presents two SVG charts built with D3.js v7, both visualizing daily sales trends for three series (A, B, C) from `sales_trends.csv`. The top chart displays multi-series line plots, while the bottom combines bars for series A and B with an overlaid line for series C. The code uses `d3.csv` with `d3.autoType` for data loading, `d3.scaleTime` and `d3.scaleLinear` for axes, and renders interactive tooltips styled via CSS.
