This scatter plot shows the relationship between petal length and sepal length for 150 iris flowers, with each flower represented as an orange circle. Built with vanilla HTML and D3 v6, the visualization uses `d3.scaleLinear` to map the data ranges to SVG coordinates, and `d3.axisLeft` and `d3.axisBottom` to render labeled axes. The data is loaded asynchronously from a remote CSV file via `d3.csv`, and the plot fills the browser window. The code explicitly sets axis text to 30 pixels for readability.
