This scatter plot shows the relationship between sleep duration and age, with each point representing an individual’s reported hours of sleep plotted against their age. The visualization uses a reusable `scatterPlot` function built with D3 v6, which configures linear scales for both axes, draws circles with a fixed radius, and appends axis labels. Data is loaded asynchronously via `d3.csv` from a remote gist URL, with numeric parsing applied to the `Sleep Duration` and `Age` fields. The SVG fills the entire browser window, and the chart is rendered using standard D3 selections and joins.
