This is a scatter plot that compares the GDP per capita and life expectancy of countries for the year 2007, with the size of each circle representing the country's population. The SVG is rendered using Svelte, with a `Datapoint.svelte` component drawing semi-transparent circles. The code uses D3's `scaleLinear`, `scaleSqrt`, and `scaleOrdinal` to map the data to positions, radii, and continent-based colors. The data originates from the Gapminder dataset, which is loaded from a CSV file.
