A scatter plot of time-series data from the Iris Dataset, showing Value over Time for each observation. D3's `scaleLinear` maps data to SVG coordinates, with axes rendered by custom components. The `Marks` component draws a black line connecting points and circles with tooltips using `d3.line`. Data is loaded asynchronously from a CSV URL via `d3.csv`, and the visualization is built with React and rendered as SVG, styled with the Poppins font.
