This dashboard, built with Vue and D3 v7, visualizes a dataset of car owners from CSV data, allowing users to filter by country. It displays four coordinated views: 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 counts to average manufacture year. The visualization uses D3's `d3.rollups`, `d3.scaleLinear`, `d3.line`, and SVG rendering to create interactive charts with tooltips, while a dropdown menu drives the country-based filtering.
