This example demonstrates a static SVG drawing of a red-brown cat created with D3.js v7. The visualization shows the cat’s body as an ellipse centered in a 400x400 viewport with a light green background. The code appends an SVG element using `d3.select` and `append`, then sets geometric attributes like `cx`, `cy`, `rx`, and `ry` along with a fill color. It serves as a minimal fork of D3 transitions, focusing on basic shape rendering rather than animated behavior.
