This visualization analyzes daily sales, revenue, and profit trends using two D3.js v7 SVG charts. A multi-series line chart displays all three metrics over time, while a combined chart overlays sales as bars with a profit line, both featuring custom tooltips and a styled interface using the Poppins font. The code loads CSV data via `d3.csv`, constructs scales with `d3.scaleTime` and `d3.scaleLinear`, and renders paths and bars with `d3.line` and `d3.axisBottom`, applying color-coded series and gridlines for readability.
