This dashboard visualizes flight data using D3 v4 and Dimple, with ten SVG charts. It displays yearly flight totals as bars, the proportion of on-time versus cancelled flights as a pie chart, and cancelled flight counts by year and by cancellation code. Additional bar charts break down flight volume by month, day of month, and day of week. The data is loaded from JSON files and rendered with dimple.js, with custom red series styling for highlighted circles.
