Fork of Circles with D3
This example uses D3 to draw a winter scene composed of two penguins and a snowman, all constructed from individual SVG circles. The code defines each character through functions that return arrays of circle objects, with properties for position, radius, and fill color. The `select`, `selectAll`, `data`, and `join` methods bind this data to SVG elements, setting attributes like `cx`, `cy`, `r`, and `fill` dynamically. It demonstrates D3’s data-binding pattern for creating and styling multiple shapes from a single dataset.
