This example visualizes the distribution of penguin species from the "penguins_size" dataset as a pie chart. It shows the relative counts of each species, with labels displaying the species name and its percentage share. The visualization is built using D3.js v7, creating an SVG pie chart with slices colored via `d3.scaleOrdinal` and the `d3.schemeCategory10` palette. The chart also includes a legend and title, with data loaded asynchronously from a remote CSV file.
