Now let me check the actual SQL to understand the exact data structure needed:

Let me read the current scenario page to understand what to keep and what to remove:

Good! Now I understand the structure. Let me create a comprehensive implementation plan using EnterPlanMode:

Now let me start by creating the new chart components. First, let me create the Radar Chart component:

Now let me create the Head-to-Head Bar Chart component:

Now let me create the Convergence by Scenario grouped bar chart:

Now let me create a Histogram component for the Scenario page:

Now let me update the leaderboard component to use horizontal bar chart instead of table. First, let me read the current one:

Now let me create an updated leaderboard component with horizontal bar chart and collision-free toggle:

Now let me update the Overview page to use the new radar chart and horizontal leaderboard:

Now let me completely rewrite the Scenario page to show only the Deep Dive with box plots and histogram:

Now let me replace the entire Scenario page with the Deep Dive version:

Now let me update the Algorithm page to show the Head-to-Head bar charts:

Now let me create the Run Metadata Card and Visualization Replay components for the Inspector page:

Now let me create the Visualization Replay component:

Now let me update the Inspector page to add these components with cascading filters. Let me read the current inspector page:

Let me create a new Inspector page with Run Metadata Card and Visualization Replay:

Now let's test the build:

Excellent! The build succeeded. Now let me restart the dev server and verify everything is working:

Let me verify the server is running:

The server is running and serving pages successfully. Now let me complete the todo list:

All tasks are complete. Here's a summary of what was implemented:

Implementation Complete

I've successfully built all the requested features across the dashboard:

Overview Page

• ✅ Added Radar Chart showing normalized metrics comparison across all algorithms
• ✅ Replaced leaderboard with horizontal bar chart visualization
• ✅ Added collision-free toggle to filters
• ✅ Kept KPI cards with dynamic filtering

Scenario Page - Deep Dive

• ✅ Simplified to show only Scenario Deep Dive analysis
• ✅ Added box plots for all 4 metrics (convergence, path length, steps, compute time) × algorithms
• ✅ Added histograms showing metric distributions for the selected scenario
• ✅ Implemented cascading filters: Scenario selector + Algorithm multi-select
• ✅ Removed all other charts and data

Algorithm Page - Head-to-Head Comparison

• ✅ Created Head-to-Head Bar Charts for 4 core metrics (convergence, path length, steps, compute time)
• ✅ Added Convergence by Scenario grouped bar chart
• ✅ Implemented collision-free toggle filter
• ✅ Added algorithm focus selector
• ✅ Removed all previous box plots and complex charts

Inspector Page - Run Inspector

• ✅ Created Run Metadata Card with 3-column layout:

  • Outcome metrics (convergence, path length, steps, compute time, collisions)
  • Hyperparameters (algorithm-specific config)
  • Configuration (init/desired poses, map size, resolution)
• ✅ Built Visualization Replay with synced timeline charts
• ✅ Implemented cascading filter dropdowns: Algorithm → Scenario → Run ID
• ✅ Added metric overlay selector for timeline visualization
• ✅ Included playback controls (play/pause, step through, speed control)

All new components use Recharts for visualization and are fully responsive. The application builds successfully and runs without errors.
