This dashboard example, built with Vue and D3 v4, presents multiple data visualizations from a CSV file of sales records. The primary chart is a stacked bar chart that breaks down sales by product category, using a color-coded system to distinguish between subgroups. It imports specific D3 functions like `csv`, `scaleBand`, and `scaleLinear` to parse the data and construct the SVG-based charts. The interface uses a CSS grid to arrange four distinct visualization panels, with a tooltip element prepared for interactive data exploration.
