This example displays a dataset summary alongside a static SVG composition of colored circles. It loads a hosted CSV file of global economy data and computes basic statistics for numeric columns, including row count, min, max, and mean. The visualization renders a 3-by-10 grid of circles using D3 v7’s selection and data-joining methods, applying a Tableau color scheme and decorative opacity. The code uses `d3.csv` for parsing and `d3.min`, `d3.max`, and `d3.mean` for summary calculations, with all output drawn as SVG elements.
