Fork of Circles with D3
This visualization demonstrates D3’s data-join pattern by rendering a set of seven semi-transparent circles of varying radii and colors onto an SVG canvas. The circles are positioned according to hardcoded coordinates from the example data, with each circle’s fill color and opacity set through chained attribute methods. The code uses `select`, `selectAll`, `data`, and `join` from D3 7 to create and size the SVG element dynamically based on the container’s dimensions.
