Convert Dash dashboard to Streamlit with Folium route map

[Copilot]

Replace the Dash-based dashboard with Streamlit, preserving all 7 Plotly chart functions unchanged and adding the Folium route map from the notebook.

dashboard.py

• Swap from dash import Dash, dcc, html → streamlit, folium, streamlit_folium
• Add @st.cache_data to all data/chart/map functions
• Replace create_dashboard() Dash layout with st.tabs / st.plotly_chart in main()
• Add build_route_map() — exact Folium map from the notebook (city coords, PolyLine routes color-coded by transport mode, CircleMarkers)

tab1, tab2, tab3, tab4, tab5 = st.tabs([
    "🚦 Traffic & Time", "📊 Demand & Preferences",
    "💰 Budget & Satisfaction", "🔀 Cost Breakdown", "🗺️ Route Map",
])

New files

• requirements.txt — streamlit, pandas, plotly, scikit-learn, folium, streamlit-folium
• .streamlit/config.toml — theme + headless server config
• README.md — features, local run, Streamlit Cloud deployment
• .gitignore — Python/Jupyter/OS artifacts

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• checkip.amazonaws.com
  • Triggering command: /home/REDACTED/.local/bin/streamlit streamlit run dashboard.py --server.headless true --server.port 8501 (dns block)
  • Triggering command: /home/REDACTED/.local/bin/streamlit streamlit run dashboard.py --server.headless true --server.port 8502 --server.address 0.0.0.0 (dns block)
• github-production-user-asset-6210df.s3.amazonaws.com
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
