A pet adoption dashboard displays summary statistics and a bar chart of average adoption fees by pet type. It loads CSV data from a GitHub gist via `d3.csv`, then renders the total pet count, average fee, and average age in a card layout. The bar chart uses `d3.scaleBand` and `d3.scaleLinear` to encode the average fee per pet type as SVG rectangles, with labels showing dollar values. The interface is built with plain HTML and CSS, relying on D3 v7's DOM selection and data join APIs.
