This example presents a scatter plot of penguin data, using D3.js version 5 within a React framework. It visualizes the relationship between flipper length and body mass, with additional ellipse-shaped points encoding culmen length and depth through the `rx` and `ry` attributes. The SVG chart uses `scaleLinear`, `axisLeft`, and `axisBottom` for axes, styled with cursive fonts and a labeled title. Data is loaded as CSV from a GitHub gist, with numeric fields parsed for the plot.
