Use Cases

ChartGen is versatile and covers three main pillars of data management:

Data Analysis: Perform statistical operations such as filtering, aggregating, and custom calculations. Ideal for cleaning datasets or finding specific aggregates.
Data Interpretation: Go beyond raw numbers by using the AI to identify patterns, evaluate trends, and generate comprehensive reports that explain data anomalies.
Data Visualization: Convert complex datasets into visual formats like bar, line, pie, or scatter charts. This is perfect for dashboards and presentation materials.

Example Prompts

"Analyze the attached quarterly_sales.xlsx file and calculate the total revenue per product category."
"Interpret the growth trends in this data and provide a brief report on why Q3 showed a decline."
"Generate a stacked bar chart displaying market share distribution from the provided JSON data."

Tips & Limitations

Credit Management: Each tool call consumes 20 credits. Free accounts receive 200 credits monthly; monitor your usage via the ChartGen billing dashboard.
Data Input: Ensure your files are formatted correctly as .xlsx, .xls, or .csv. For JSON input, provide a valid structured schema to ensure the AI parses the attributes correctly.
Mutually Exclusive Parameters: Use either the --file flag or the --json flag, but never both in the same command execution.
Privacy: Since this tool utilizes an external API, verify that sensitive data is handled in compliance with your organization’s security policies.
