lets make a face
This example builds a simple cartoon face in an SVG using D3 v5. It starts with a red background and appends a large yellow circle for the face, then adds two smaller black circles for the eyes. The code uses basic D3 selection and attribute methods—`d3.select`, `svg.append`, and `.attr`—to position shapes with explicit coordinates. The data is hardcoded, and the rendering relies on SVG elements within a React framework, though the visualization itself does not use any data binding or interactive features.
