Thought I'd post here about developing Custom Visualizations with Preact (and Sass), a significantly smaller pseudo-framework than React that works in a similar manner but with fewer hiccups in Custom Visualizations. This can make development a lot smoother. If you're interested in how to do this, you can check out my blog post on it: https://motorcitycoder.wordpress.com/2024/12/19/ibm-cognos-customvis-with-preact/
