Present

Present — HTML Visualization

When to use

• User writes /present or asks to format something visually
• Need to visualize data, a lesson, report, plan, or comparison
• Request for an HTML file to view in a browser

Process

1. Determine content type — lesson, report, data, plan, comparison, roadmap
2. Gather content — from the conversation, files, or generate it
3. Create HTML using the design system below
4. Save as present-{topic}.html in your working directory
5. Send to the user (as a document attachment or file)
