Quick Start
1. Visualize a CSV file
Visualize this data: [paste CSV or provide file path]
The agent will:
- Parse the data (CSV, JSON, or raw text)
- Analyze column types (numeric, categorical, temporal)
- Recommend the best chart type
- Generate an interactive visualization
2. Create a specific chart
Create a bar chart comparing Q1-Q4 revenue for 2024 and 2025
3. Build a dashboard
Build a dashboard from sales-data.csv with:
- Revenue trend (line chart)
- Regional breakdown (pie chart)
- Product comparison (bar chart)
