D3 and React both want to control the DOM. The solution is to let D3 handle calculations (scales, paths, layouts) while React handles rendering.

Step 1: Setup

Install d3-scale, d3-shape, d3-array - the calculation modules. Skip d3-selection since React handles DOM manipulation.

Step 2: Create Scales

Use useMemo to create D3 scales from your data. Scales transform data values to pixel coordinates.

Step 3: Render with React

Map your data to SVG elements. Use D3 scales to compute positions. React re-renders when data changes, D3 recalculates coordinates.
