A D3 area chart displays loan amounts against borrower age, showing how requested loan values distribute across ages 21–26 with a prominent cluster between high and low amounts. The visualization sorts the dataset by age, encodes age on a linear x-scale and loan amount on a linear y-scale, and renders a steelblue filled area via the `d3.area()` generator with axes from `d3.axisBottom` and `d3.axisLeft`. The example uses D3 v7 with SVG rendering, drawing from an inline array of sample data.
