This scatterplot displays the relationship between health and population from the Gapminder health-income dataset, with each point representing a country. The visualization uses D3 v7 to fetch CSV data, scale both axes linearly based on the data extent, and render points as SVG circles. Axes are added using `axisLeft` and `axisBottom` from D3's scale API, with data mapped through `scaleLinear` and the extent function. The chart fills the entire browser window, with custom margins and styled tick text.
