create-viz

create-viz is a skill for Claude Code from nota-america/forgecat-agent-profiles. It costs 55 tokens per session (1,226 once invoked), scanned A, a copy of create-viz, Apache-2.0.

A workflow for creating publication-quality charts in Python from query results, pasted data, or files such as CSV and Excel. It can also create interactive charts with features such as hover details and zooming.

In plain words
What is it for?
Use it to build charts from data, clean and prepare the input, select a suitable visualization, or create an interactive chart.
Why use it?
It reduces the work of preparing data, choosing an appropriate chart, and formatting the result for a report, presentation, or dashboard.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

create-viz scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

/create-viz - Create Visualizations

If you see unfamiliar placeholders or need to check which tools are connected, see CONNECTORS.md (.forgecat/profiles/@forgecat/anthropics_knowledge-work-plugins_data/CONNECTORS.md).

Create publication-quality data visualizations using Python. Generates charts from data with best practices for clarity, accuracy, and design.

Usage

/create-viz <data source> [chart type] [additional instructions]

Workflow

1. Understand the Request

Determine:

  • Data source: Query results, pasted data, CSV/Excel file, or data to be queried
  • Chart type: Explicitly requested or needs to be recommended
  • Purpose: Exploration, presentation, report, dashboard component
  • Audience: Technical team, executives, external stakeholders

2. Get the Data

If data warehouse is connected and data needs querying:

  1. Write and execute the query
  2. Load results into a pandas DataFrame

If data is pasted or uploaded:

  1. Parse the data into a pandas DataFrame
  2. Clean and prepare as needed (type conversions, null handling)

If data is from a previous analysis in the conversation:

  1. Reference the existing data

3. Select Chart Type

If the user didn't specify a chart type, recommend one based on the data and question:

Data Relationship Recommended Chart
Trend over time Line chart
Comparison across categories Bar chart (horizontal if many categories)
Part-to-whole composition Stacked bar or area chart (avoid pie charts unless <6 categories)
Distribution of values Histogram or box plot
Correlation between two variables Scatter plot
Two-variable comparison over time Dual-axis line or grouped bar
Geographic data Choropleth map
Ranking Horizontal bar chart
Flow or process Sankey diagram
Matrix of relationships Heatmap

Explain the recommendation briefly if the user didn't specify.

4. Generate the Visualization

Write Python code using one of these libraries based on the need:
