This interactive bubble chart displays the frequency of AI features for photographers, using bubble size to represent value and color to indicate rating (green=high, orange=medium, red=low). Built with React and D3 v7, the visualization renders SVG circles through the `renderCircles.js` module, which applies `scaleLinear` for positioning and sizing. Clicking a bubble selects it (turning white), while hovering triggers a 20% radius expansion via CSS transitions. Data loads from `data.csv` into the React app, with D3's `select` and `join` APIs handling dynamic circle and label updates.
