Fork of Circles with D3
This example uses D3 to render five semi-transparent colored circles of varying sizes across an SVG canvas. Each circle’s position, radius, and fill color are specified in a static data array, and the code joins this data to `circle` elements via `d3.select` and `selection.join()`. The visualization highlights basic SVG shape creation and data binding, with an opacity of 0.435 applied uniformly. The example serves as a minimal template for users to fork and modify with creative themes, as suggested in the accompanying challenge.
