High-Contrast Graphic Poster Portrait

Data Visualization

Generate visualizations based on user-provided data that conform to the Storytelling with Data (SWD) principle. Triggering conditions: This skill must be used when a user provides data and requests "draw a chart," "generate a chart," "visualize," "make a graph," or "show me this data," or uploads CSV/Excel/spreadsheet data and wants to see a graphical representation. Even if the user only says "analyze this data" and the data is suitable for visualization, this skill should still be used to generate a chart.
