apexcharts.js VS victory

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.

ApexCharts is a modern charting library that helps developers to create beautiful and interactive visualizations for web pages. It is an open-source project licensed under MIT and is free to use in commercial applications.

Victory is a set of modular charting components for React and React Native. Victory makes it easy to get started without sacrificing flexibility. Create one of a kind data visualizations with fully customizable styles and behaviors. Victory uses the same API for web and React Native applications for easy cross-platform charting.

Victory Native is a chart library that was developed in 2015. It has been 7 years since its inception. With a high cumulative download count of 7,434,044, it has garnered an impressive 10.3k+ stars on GitHub. It is the longest-standing and most widely used chart library in the history of React Native.

Anyone use Victory? It looks like it is gaining traction.

For convenience of others, here’s a link to Victory Native’s project site (it’s a react.js library with a native version, so be sure to find the native docs).

Victory is a ReactJS and React Native chart library created by Formidable. It's based on ReactJS and D3, and comes with a slew of fully configurable charts pre-installed.

I've enjoyed using Victory - needs React tho: https://formidable.com/open-source/victory/

Victory is great, it doesn't officially support React 18 yet, you'll get warnings because the peer version is still looking for React 17, but it shouldn't be an issue if you force install. It's really just that the tests won't work with React 18, but it should be fine to use it in your project.

They have an open issue for React 18 support, but they are stuck because they are using Enzyme for unit tests (which is effectively obsolete and will likely never work with React 18). So their plan appears to be to move from Enzyme to RTL first and then support React 18.
