Build an interactive dashboard for one week of a city bike-share scheme from the exact dataset below (CSV: trips started per hour, one row per day, columns h00 to h23). Embed the data in the page verbatim and compute every number from it; do not invent or alter any value.

The dashboard needs: a 7 x 24 heatmap (days by hours) with a clear colour legend; a line chart of the average hourly profile for weekdays versus the weekend; a bar chart of total trips per day; KPI cards for total trips, the busiest day, and the single busiest hour of the week (day and hour); and an automatic callout that spots the anomaly in the data (one weekday evening that is far below the other weekdays at the same hours) and names it. Clicking a day highlights that day's row in the heatmap and draws its hourly line over the profile chart; hovering any heatmap cell shows its exact count. Draw the charts yourself with SVG or Canvas. So the page is alive without input, on load the heatmap fills in hour by hour like a clock sweeping across the week (about 5 seconds), then the anomaly callout appears. Make it look like a polished product, readable on desktop and phone.

Save it as index.html in the current directory: one self-contained file with inline CSS and JavaScript only, no libraries or frameworks, and no external requests of any kind (no CDNs, web fonts, images or audio files). It must work when opened directly from disk, fit any window from a 390 px wide phone to a desktop, and run without console errors. You may serve it locally and open it in headless chromium (/usr/bin/chromium, software WebGL, no GPU) to screenshot and inspect your own output, and iterate on your own before finishing. Close any browser you open as soon as you've taken your screenshot.
