This dashboard visualizes car data from a CSV file, filtering by country to show four coordinated charts: a line chart of cars manufactured over time, a bar chart of top car brands, a pie chart of car color counts, and a scatter plot comparing brand count against average year of manufacture. The visualizations are built using D3.js v7 with SVG rendering, leveraging scales such as `d3.scaleLinear` and `d3.scaleOrdinal`, as well as `d3.rollups` for data aggregation. A dropdown selector and tooltip enhance interactivity.
