Add Streamlit dashboard for scouting data analysis

[Copilot]

Implements interactive Streamlit dashboard with three analysis interfaces: team performance metrics, match outcome prediction, and raw data export.

Implementation

Team Analysis Tab

• Sidebar team selector with cached queries
• Metric cards: avg auto/teleop scores, climb percentage
• Plotly line chart for score progression across matches
• Alliance distribution viz (placeholder for position heatmap - schema lacks x/y coords)

Match Predictor Tab

• Multi-select alliance inputs (3v3)
• Aggregate average scoring prediction
• Horizontal stacked bar chart for win probability
• Expandable team breakdown

Raw Data Tab

• Sortable/searchable dataframe with native Streamlit controls
• CSV export via download button
• Summary stats (matches/teams/records)

Zero-Match Safety

All queries use defensive COUNT check pattern:

check_query = "SELECT COUNT(*) as count FROM scouting_data WHERE team_number = ?"
count_df = pd.read_sql_query(check_query, conn, params=(team_number,))

if count_df['count'].iloc[0] == 0:
    return None  # Handled gracefully in UI

Prevents crashes on non-existent teams or empty database states.

Code Organization

• Extracted CLIMB_LEVELS constant to eliminate duplication across queries
• @st.cache_data decorators on all database operations
• Separate tab functions for maintainability

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)

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)

Original prompt

Create a dashboard.py file using the Streamlit library. Connect it to the scouting_data.db SQLite database. Create the following three tabs:

'Team Analysis': A sidebar dropdown to select a Team Number. Display their statistics:

    Metric Cards: 'Avg Auto Score', 'Avg Teleop Score', 'Climb %'.

    Line Chart: Score evolution over match numbers.

    Heatmap Placeholder: A scatter plot of their starting positions (if available).

'Match Predictor': Two multi-select inputs: 'Red Alliance' (select 3 teams) and 'Blue Alliance' (select 3 teams).

    Calculate the sum of the averages for both alliances.

    Display a 'Predicted Winner' and 'Win Probability' bar chart.

'Raw Data': A sortable dataframe view of the entire database with a 'Download CSV' button.

Constraint: Ensure the SQL query handles cases where a team has zero matches played without crashing."
