Pts.js: a modular librairy for visualization and creative coding

Hi HN, Pts is one of my late-night personal projects :)<p>Thanks for posting. Happy to answer any questions.

Wow. High quality stuff. Great API. Lots of demos! (<a href="https:&#x2F;&#x2F;ptsjs.org&#x2F;demo&#x2F;?name=sound.freqDomain" rel="nofollow">https:&#x2F;&#x2F;ptsjs.org&#x2F;demo&#x2F;?name=sound.freqDomain</a> is the best).

The API seems much more intuitive than that of D3.js!<p>I used D3.js originally to draw line charts to visualise USGS mineral statistics, but currently only use it for svgLine (from d3-shape) and scaleLinear and scaleLog (form d3-scale) functions.<p>Is drawing on canvas much faster than on SVG?<p>Could matrix or other transforms be used to map screen coordinates to chart coordinates as the d3 scales do?<p>Generic projections in complex plane (viewed as cartesian or polar coordinates) might be fun for generative art or visualisations of various signals.

The demos are very fun to play with, and I was surprised how brief the code was for each one... would be great to see a comparison to similar librairies

Really cool stuff! The touch detection on mobile seems to be a bit wonky when I scroll through.

Upvote for the typo in the title. That&#x27;s how my mom says it.

For people interested in creative coding and data driven visualizations there is also the thi.ng umbrella [1] which provides a large collection of modular micro utilities.<p>Many of them are clojure inspired and are written in functional-style typescript.<p>A lot of these utilities (eg. transducers, multi-methods, stream utilities etc.) are very useful outside the data-visualization space as well.<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;thi-ng&#x2F;umbrella&#x2F;" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;thi-ng&#x2F;umbrella&#x2F;</a>

It would be cool to see a comparison between this and existing libraries like p5.js.

This is actually such great work. Great examples (they look good don&#x27;t just read good ;)) and an attractive API. You&#x27;re a talented developer!

feels like paper.js and processing had a child. cool stuff!

Insanely cool, thanks. I have been looking for something to use on my profile, blog etc, this is perfect.

Can&#x27;t stop thinking about out post and telecommunication board.

Title has a very airy typo.<p>Also, my new favorite library.
