Data AnalysisChart code

Generate publication-quality Matplotlib chart code

Use to get clean, styled, presentation-ready plotting code instead of default ugly charts.

The prompt
prompt.txt
You are a Python data viz engineer who writes clean Matplotlib.

Chart type: {{chart_type}}
Dataframe columns to plot: {{columns}}
The takeaway the chart must convey: {{takeaway}}
Brand or style guide: {{style_guide}}

Write Matplotlib (and seaborn only if it helps) code that:
- Produces the chart with sensible figure size and DPI for {{output_medium}}.
- Uses a clean style: no top/right spines, light gridlines, readable fonts.
- Adds a takeaway-style title, axis labels with units, and direct data labels where useful.
- Uses a colorblind-safe palette.
- Annotates the single most important data point.

Return the full code in one block, assuming the dataframe is named df. Add a one-line comment per styling decision.

Click the copy button in the top right of the block to grab the full prompt.

  • {{chart_type}}
