Workshop @ VizChitra 2025

Prompt-to-Plot: Crafting Visual Stories with LLMs

In this hands-on workshop, you’ll go from zero to a live data visualization using only natural-language prompts (plus a dash of copy-&-paste). Turn raw data into a compelling narrative—all by chatting with an LLM.

No coding knowledge is required (but it’ll help a lot.)

We strongly recommend getting a ChatGPT Plus ($20) or higher account and play with it before the session. Specifically, upload a CSV into it, use O3 as the model, and ask it to write code to analyze and create visual stories. Examples:

• Weight Loss
• Employment Trends

No API key required but you’re welcome to bring your own.

This will be an end-to-end workflow that designers, developers and data enthusiasts can follow verbatim.

What we’ll cover

• Prompt engineering for analysis and chart code
• Iterative refinement, so your axes, labels and colors actually make sense
• Conversational debugging: when the output isn’t quite right, ask the LLM to fix it
• Deploy in minutes: publish without writing a CI script
• Advanced hacks: embed your chart in a blog, automate periodic updates

Takeaways

• A fully functioning, deployed visualization you can share immediately
• A “prompt recipe” library for future charts and dashboards
• Best practices for designer–developer collaboration via LLMs
• Confidence in using LLMs as a reliable coding partner

About the Instructor

Anand is an LLM psychologist at Straive. (It’s not an official title. He just calls himself that.) He co-founded Gramener, a data science company that narrates visual data stories, which Straive acquired. He has hand-transcribed every Calvin & Hobbes strip ever and dreams of watching every film on the IMDb Top 250.
