AI Charts That Look Like a Designer Made Them

lieflat-charts gives AI coding agents a consistent visual style, so every chart they produce looks intentional — not like something an algorithm threw together.

The problem nobody talks about

When you ask an AI coding agent to create a chart, it makes one up. Colours, fonts, layout — all invented on the spot. The result often looks fine in isolation, but put three charts side by side and they feel like they came from three different companies.

That inconsistency isn't just aesthetic. It signals to clients, investors, or your own team that no one was really in charge of the output.

What lieflat-charts does

It's a collection of chart design rules that your AI agent can follow instead of improvising. Once it's set up, the agent automatically chooses the right style based on what you're showing: clean, annotation-rich layouts for research reports; bold numbers and big bars for dashboards; flowing diagrams for processes and relationships.

Colours are chosen by meaning, not by whim. The finished charts open directly in a browser — no extra software, no installation. Just double-click the file.

Over 3,200 people have saved this project on GitHub in a very short time, which says something.

Why it matters for your business

If you're already using an AI agent to help with reports, proposals, or client dashboards, this is the difference between output that looks generated and output that looks produced. Your brand deserves the latter.

Worth asking whoever helps you with AI tools: can we add a visual standard like this to what we're already using?

Words worth knowing

AI coding agent — An AI assistant that doesn't just answer questions but actually writes and runs code on your behalf. Think of it as a junior developer you can give tasks to.

Agent skill — A set of instructions or rules you give an AI agent so it behaves consistently in a specific area — like always following your brand colours, or always citing sources.

HTML file — A single document a browser can open. No app needed, no account, no upload. It lives on your computer and works offline.

Design language — A shared set of visual rules (colours, spacing, type) that makes everything from the same source feel like it belongs together. Big brands spend a lot on this. This tool gives it to you for free.
