This example demonstrates a multi-chart interactive dashboard for exploring vehicle traffic data from the Lekagul sensor dataset. It uses crossfilter to enable linked filtering between a time series chart, two bar charts, and a scatter plot, all rendered as SVG. The time series chart provides brush-based time range selection, while bar charts for car type and gate name respond to mouse hover events. The visualization is built with D3.js and leverages its modular chart functions including `d3.brushX`, `d3.axisBottom`, and `d3.scaleBand` to coordinate user interactions across all views.
