This visualization reproduces a Sol LeWitt art piece by rendering four semi-transparent circles of varying radii and colors onto an SVG canvas. Built with D3.js, the code uses the `select` and `join` APIs to manage the SVG container and circle elements, positioning them via `cx`, `cy`, and `r` attributes. The circles overlap with a fixed opacity value, creating layered intersections that mimic the geometric style of the original artwork. The composition is static, with no interaction or animation, and the data is hardcoded in an array of objects within the `index.js` file.
