What you can build

  • Build a sketch that combines shapes, color, and variation to produce original poster compositions.
  • Create a browser-based artwork that changes in response to visitors’ mouse or keyboard input.
  • Turn a small dataset into an exploratory visual sketch with a presentation tailored to the subject.
  • Make an audiovisual web experience that connects visual composition and sound.
  • Develop a small interactive sketch that learners can modify while exploring drawing and programming.

Try this prompt

Create a small p5.js sketch for an interactive generative poster. First inspect the existing project and preserve unrelated files and assets. Implement a canvas with a restrained color palette and a few controls that change the composition; keep the sketch’s parameters understandable and easy to adjust. Explain how to run it using the project’s documented setup, and note any assumptions. Do not add services or dependencies unless needed.

Get started

  1. Open the web editor

    Use the p5.js web editor linked from the README to start a browser-based sketch without setting up a local project.

  2. Make a first sketch

    Follow the official Get Started tutorial; its starter example uses setup() to create a canvas and draw() to update it.

  3. Move to a web project

    For local development, follow the project’s official Get Started tutorial and reference; choose the setup path documented there for your project.

License & notes

LGPL-2.1The library is free and open source under LGPL-2.1. Browser execution and any hosting are separate costs; no paid API or model is required by the documented workflow.

  • Focused on browser-based creative coding, not a complete application backend or a turnkey charting product.
  • Using or distributing the library is subject to LGPL-2.1; review its linking and redistribution obligations, especially when modifying or distributing the library. Hosting costs depend on your deployment choice.
