Fork of Circles with D3
This example demonstrates the D3 General Update Pattern by rendering a set of seven circles of varying sizes and neon colors onto a light green SVG background. It uses D3's `select`, `join`, and attribute methods to bind an array of objects containing `x`, `y`, `r`, and `fill` properties to circle elements. The circles are positioned at fixed coordinates, with each radius ranging from 20 to 147 pixels and a uniform opacity of 0.7. The code showcases method chaining and dynamic styling with data-driven attributes.
