p5.js
p5.js is a client-side JS platform that empowers artists, designers, students, and anyone to learn to code and express themselves creatively on the web. It is based on the core principles of Processing. Looking for p5.js 2.0? http://beta.p5js.org
P5.js is pretty great.
I used it create art, basically taking animal photos and using the dna sequence from that animal to recreate the photo using the 4 letters. (I did four passes using different size letters and layered in Gimp). People seem to like them, and they got into an art:science show.

Coding train has a lot of videos on using p5.js

ApexCharts is an excellent library for creating interactive charts, and integrating it in [Vue.js (https://vuejs.org) is really a piece of cake. However, when it comes to displaying a time-series chart with thousands of points, the performance can suffer, sometimes causing the page to freeze during the rendering or when the user zooms or navigates through the data.

Project mention: Type-Safe SVGs with Mirrow: A New DSL for Modern Frontend Graphics | dev.to | 2025-09-25
I started developing Mirrow after growing increasingly frustrated with the current vector graphics landscape. We have a plethora of JavaScript libraries like GSAP and Snap.svg which excel at manipulating SVGs at runtime, and they serve their purposes well.

I am using https://js.cytoscape.org/ to render this json file on the website.
