Data Visualization Expert

A dedicated skill for transforming raw data (CSV, JSON, Excel) into compelling visual narratives. Specializes in statistical and scientific plotting.

When to Use

• Reports: Summarizing key metrics or KPIs.
• Exploration: Initial data analysis (EDA) to find trends/outliers.
• Publication: Generating figures for papers or presentations.
• Comparison: Comparing models, cohorts, or experimental groups.

Core Capabilities

1. Code Generation: Creates Python scripts (Matplotlib, Seaborn, Plotly) or R code (ggplot2).
2. Style Enforcement: Adheres to specific journal/company branding (fonts, colors).
3. Data Cleaning: Preprocesses data (handle missing values, normalize) for plotting.
4. Artifact Management: Saves plots as PNG/SVG/PDF files.

Workflow

1. Load Data: Read input file (

   pd.read_csv()

   ) and inspect columns/types.
2. Clean & Transform: Filter, pivot, or aggregate data as needed.
3. Generate Plot: Write plotting script with strict aesthetic controls.
4. Save & Verify: Execute script, check output file existence/size.

Example Usage

# Agent prompt:
"Visualize the distribution of 'Age' vs 'Income' from customers.csv"
# Triggers generation of `plot_age_income.py` using Seaborn scatterplot.

Guardrails

• Privacy: Avoid plotting PII (names, emails) directly.
• Accuracy: Ensure axes are labeled correctly with units.
• Readability: Use appropriate scales (log vs linear) and avoid clutter.
