CanvasXpress FAQs

Question 1

Can CanvasXpress integrate with my own datasets?

Accepted Answer

Yes, it supports validation against your own data. You can provide column headers, full data arrays, and even specific column types (string, numeric, factor, date) to ensure the generated configurations accurately reflect your data structure and intent.

Question 2

Do I need CanvasXpress charting expertise to use this tool?

Accepted Answer

No, that's one of CanvasXpress's core benefits. You can describe your desired chart in plain English, and the tool handles the complexity of generating the correct JSON configuration, making advanced data visualization accessible.

Question 3

How does CanvasXpress generate accurate chart configurations?

Accepted Answer

It employs a sophisticated process involving semantic vector search to match descriptions with few-shot examples (RAG), a tiered system prompt for optimal LLM token usage and relevance, and rigorous validation of generated configurations against provided data headers or arrays.

Question 4

Is there a way to understand how the AI generates a configuration?

Accepted Answer

Absolutely. By enabling debug mode (`CX_DEBUG=1`), you can trace the entire process, including retrieval results, the prompt sent to the LLM, token usage, the raw LLM response, parsed config, and the detailed header validation steps.

Question 5

What is CanvasXpress and what does it do?

Accepted Answer
