This D3.js v7 example summarizes a remote Retail Sales CSV dataset and visualizes the first ten records as a bar chart using `d3.scaleBand` and `d3.scaleLinear`. The page also renders two decorative SVG illustrations—a car and a smartphone—drawn with primitive shapes like `rect` and `circle`. The dashboard displays dataset statistics in a styled summary box and uses `d3.axisBottom` and `d3.axisLeft` for chart axes.
