Fork of Circles
This visualization demonstrates how to create and style SVG circles using D3.js, binding data to DOM elements to control their positions, sizes, and colors. The code imports the `select` function from D3 and uses the general update pattern with `selectAll`, `data`, and `join` to dynamically create the SVG and circle elements. It sets width and height attributes based on container dimensions, then binds an array of objects with `x`, `y`, `r`, and `fill` properties to render the circles. The example showcases method chaining and dynamic styling, with a README offering customization challenges.
