What it does
Pick a model year, a manufacturer or a car line, and the page updates its headline numbers and charts: models by manufacturer, assembly country, where engines and transmissions come from, and how much of each vehicle’s parts content is from the US and Canada. A table lists every vehicle, can be sorted, and downloads as a CSV.
How it’s built
The reports are published as PDFs, so a Python script reads them, cleans up manufacturer names and turns country codes into country names. Another script writes the result as one JSON file. The page is plain HTML, CSS and JavaScript that draws every chart in the browser, with no server and no framework.
The first version was a Streamlit app, and it is still in the repo.
Design
The interface uses a grid, hairline rules and timetable-style rows, with red as the signal color, and it works down to phone width.
