This scatter plot visualizes the relationship between bill depth and body mass for penguins, using data from the Iris Dataset. Built with React and D3, it renders circles as SVG marks positioned by linear scales, with formatted axis ticks and labels. The code imports `csv`, `scaleLinear`, `extent`, and `format` from D3 to load and scale the data, while custom React components (`AxisBottom`, `AxisLeft`, `Marks`) generate the chart elements. Styling uses the Poppins font and a teal color scheme for the marks.
