✅ Chart Generation - DEBUGGING COMPLETE

🐛 Issue Identified and Fixed

Problem

Error: "All arrays must be of the same length"
Root Cause: Mock data in ChartCreatorTool used "volumes" key but CryptoVisualizations expected "total_volumes"

Solution

# BEFORE (BROKEN):
"volumes": [[timestamp, volume], ...]

# AFTER (FIXED):
"total_volumes": [[timestamp, volume], ...]

🎯 Complete Fix Implementation

1. Model Upgrade ✅

Gemini 2.0 Flash-Lite (gemini-2.0-flash-exp)
8,192 max tokens (up from 2,048)
Higher rate limits: 30 RPM, 1M TPM, 200 RPD

2. Chart Tool Fixes ✅

Fixed volume data key: volumes → total_volumes
Structured input schema: Clean parameters instead of raw queries
Proper error handling: JSON responses with status codes
Data source auto-detection: Based on chart type

3. Agent Output Control ✅

Removed visible status codes: [SUCCESS] no longer shown to users
Clean JSON parsing: Raw JSON hidden from user interface
Clear LLM instructions: Specific format requirements for chart requests
Response cleaning: Automatic removal of raw tool outputs

4. Testing Results ✅

Direct Tool Test

✅ Chart HTML contains plotly - SUCCESS!
Status: success
Chart HTML length: 11,193 characters

Live Application Test

✅ Chart Creator tool initialized
✅ Creating price_chart chart for bitcoin with timeframe 30d
✅ Successfully created price_chart chart
