Migrating from v0.x

v1.0 replaced calling a shape as a function with an explicit .data() method, for better TypeScript support and clarity.

- const triangles = triangles3D().scale(100);
- const result = triangles(data);
+ const triangles = triangles3D().scale(100);
+ const result = triangles.data(data);

  svg.selectAll('path')
    .data(result)
    .join('path')
    .attr('d', triangles.draw);

1. ❌ Calling a shape directly, triangles(data), no longer works.
2. ✅ Call .data(data) instead.
3. ✅ Shapes are generic over their datum, see Your own data.
4. ✅ The computed properties, centroid and ccw, are included automatically.
