WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
Regarding the optimization of the effect, I found an issue on the three.js GitHub repository: https://github.com/mrdoob/three.js/issues/14104 The alpha channel issue seems to be a difficult problem, which has been present since 2018. At the end of the discussion, a solution proposed by a contributor is not to modify the UnrealBloomPass but to blend the source texture and target texture in the shader.
ChartsJS for inspiring me with the pie chart.
Project mention: Fun, Beautiful, Printable 'Story Cards' for Kids with Cloudflare AI | dev.to | 2024-04-12This AI-powered Story Card Maker is built as a SvelteKit application with Typescript. Using Flowbite Svelte component library, the whole application was laid out. The layout for the Story Card (emulating the size of a postcard - 4" x 3") is created as an HTML Canvas using Fabric.js.

Project mention: Learn SVG with 25 examples – How to code images in HTML | news.ycombinator.com | 2023-12-07As 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.

Project mention: Show HN: Minard – Generate beautiful charts with natural language | news.ycombinator.com | 2024-04-18Hi HN – Excited to share a beta for Minard, a new data visualization toolkit we've been working on that lets you generate publication-quality charts with simple natural language (throw away your matplotlib docs and rejoice!).
Upload or import CSVs, Excel, and JSON, give it a spin, and please let us know what you think! (Long format data works best for now)
For those curious, the stack is a simple Django app with HTMX/Alpine and all of the charts are specified and rendered as Vega (https://vega.github.io/vega/). Lots of LLM function calling under the hood as well.

Project mention: Show HN: A JavaScript library for data visualization in both SVG and Canvas | news.ycombinator.com | 2024-04-11> DOM-like event bubbling
This does sound very interesting. I started playing with https://two.js.org/ for a browser game but the event system proved a challange. The typescript focus also looks promising. Will give it a try.
