Wildfire Impact & Air Quality Explorer

CSCE 5320 — Assignment 4: Interactive Scientific Visualization (D3.js v7). Muhammad Zubair Hasan.

Three linked views over one year of synthetic urban sensor data (8 stations, 11,680 readings):

1. Deviation heatmap — each station-day colored by how far PM2.5 sat above or below that station's own baseline. The August wildfire-smoke episode shows up as a solid red block at ST05, ST06 and ST07.
2. Winter-vs-summer slope chart — which stations stay elevated year-round.
3. NO2 vs. PM2.5 scatter — separate trend lines for normal days and wildfire-smoke days.

Interactions: click a station (heatmap row or cell) to highlight it in every view · drag the strip under the heatmap to filter by date range · hover any mark for details · Reset dashboard clears everything.

The dataset is synthetic and was created for the course; it is not for real public-health or regulatory claims.
