Fork of Circles with D3
This example demonstrates a colorful scatter of seven circles rendered as an SVG, each positioned with explicit x/y coordinates and sized with varying radii. The visualization highlights D3.js data binding and the General Update Pattern, where an array of objects is joined to circle elements using `selectAll`, `data`, and `join`. The code sets dynamic attributes for position, radius, color, and opacity, while the SVG container is sized to match its parent element’s dimensions. A custom background color provides contrast, making the palette of vibrant fills stand out.
