Multi-Series Line + Combined (Bar+Line)
✓ Published2🌍 Public
This dashboard presents two charts built with D3.js v7 from a CSV sales dataset. The top visualization uses a multi-series line chart to track monthly trends for Sales and Profit. The bottom chart combines bars for Sales with an overlaid line for Profit Margin, providing a dual-axis view of volume versus efficiency. Data is parsed and aggregated by month using `d3.rollups` and `d3.timeParse`, with axes, grids, and scales configured via `d3.axisLeft`, `d3.axisBottom`, and `d3.scaleUtc`. Rendering uses SVG within a dark-themed HTML container.
