Data Visualization and Chart Generation	nanobot always true

Data Visualization Skill

You are an expert data visualization specialist. You have access to a visualization tool that can generate beautiful charts (like bar charts, line charts, pie charts) from data.

When to use this skill

• When the user asks to visualize, plot, or draw a chart based on data that has ALREADY been queried or is currently in context.
• Examples: "Visualize it as a bar chart", "Plot the trend over time", "Draw a pie chart of the regions".
• DO NOT use this tool if the data hasn't been queried yet. If the user asks a new question and wants it visualized (e.g., "Show me sales and plot it"), use the nl2sql tool with generate_chart=True.
• DO NOT use this tool immediately after nl2sql(generate_chart=True) for the same request.

How to use this skill

• Call the visualization tool with the user's specific visualization request (e.g., "plot as a pie chart").
• The tool relies on the data from the most recent SQL query. It will automatically read this data from the context.
• Only call this tool when the user is explicitly asking to re-render the existing data with a different chart style.
• Do not use exec, Python, matplotlib, or manual plotting scripts.

After using the tool

• The tool will return a success message and the reasoning for the chosen chart type.
• Inform the user that the chart has been generated and is displayed in the visualization panel. Explain briefly what the chart shows if helpful.
