Frappe Charts VS p5.js

As a frontend dev who also works in UX and graphics from time to time, I find it helpful to be able to do both, looking at SVGs as both a vector graphics format and a human-readable XML. IME the workflow depends more on whether any SVG is meant to be illustrative (like art) or quantitative (like charts) or interactive and animated/mutable (like a game).

For something like this bell example (https://svg-tutorial.com/svg/bell), you can certainly hand-code it if you're really math-inclined and can estimate the formulas of curves just by looking at them, but for us mere mortals, it's easier to just draw out the curves in a graphics app then export as an SVG. And for things like the ringer (is that what you call it? the orange ball thing at the bottom of the bell that strikes the bell to make the sound), being able to visually draw it on a canvas, change its size, drag it around and play with its colors and dimensions, etc. is really helpful. Figma is fine for simpler graphics, but it's really more of a UX tool than a graphic design tool, and Illustrator is a lot more powerful. Inkscape is a FOSS option.

In other circumstances, though, manipulating the SVG XML directly is also very helpful. Let's say you want to programatically generate a bar chart. If you have a big dataset, it's going to take a designer forever to manually plot them and change them every time the data changes. But it's easy for a dev to use Javascript (or any language) to draw each rectangle, programmatically adjust their heights and colors based on the data, add tooltips, etc. And that way you can dynamically update them in real-time whenever the data changes (like if the user selects a different date range, or new events come in). A lot of this is made easier by libs like https://frappe.io/charts or https://apexcharts.com. But before you take that approach, you should know that for complex charts, sometimes Canvas rendering (or just generating graphics in the backend) can be more performant than SVG.

SVGs can also be animated and interactive, not just with CSS transitions but by directly manipulating the XML geometries, like http://snapsvg.io/demos/ or https://www.svgator.com/ or https://codepen.io/collection/XpwMLO/. This is fine for product pages and such, but for really graphics-intensive apps (full games) it's probably slower than other rendering pipelines. (Not my specialty, won't speculate too much.)

TLDR Drawing them in a graphics app is usually easier for the designers, but the XML can be programmatically manipulated afterward to great effect.

Processing (P5) had this: you can select any string of text in its IDE anl search for it in the docs, and if it's one of the built-in functions or constants it will open the associated static html page that came installed with the software, so no internet nor server required. And despite being offline you can still navigate the docs too. This feels a lost basic skill in static site generation these days.

It was the only creative coding framework that had complete, offline documentation like that at the time I might add. OpenFrameworks is still mostly autogenerated stubs for example.

IMO it was one of the things that gave Processing an edge in educational contexts over all alternatives. I was pretty sad to see p5.js not fully continue that tradition and require that you go online to read the docs, and that it's not a static website but that text is rendered with javascript when you open it (still complete and with examples though).

I thought it could be funny to use the javascript version of it https://p5js.org/ in a web page and then wrap it in a Unity app, since Unity was and is the environment I use for making apps.

In this last section, I'll be creating some visual examples to show how helpful loops can be. I'll be using p5js, a JavaScript library with functionality for creative coding. That being said, I'll try to give a condensed version of the functions being utilized in the following examples.

I was curious too, took a little bit of digging :)

"the original domain of [P]rocessing was proce55ing.net, so people used to sometimes refer to processing as proce55ing or P5 or p5 for short. they still do sometimes. p5.js is a reference to that."

Processing / P5.js can be pretty fun to learn. You use a real programming language to create art and animations. With little code you can get a circle on the screen, then making it move, then following your mouse, then adding other shapes, then changing colour depending on some event… It’s conductive to experimentation and a way to gradually introduce concepts.

Then I used p5js to create the 'art' itself, really user friendly coding framework with lots of resources online! If you want to get into coding, that is a really great entry point with Daniel Schiffman's coding train videos on YT!
