We Built Our Own Chart Type for Live Dashboards
Most analytics tools give you 10–15 chart types and call it a day. But what happens when none of them actually represent your data well? We ran into this when building a CRM dashboard. We wanted to show how sales reps connect to open deals: not just totals, but actual relationships. A bar chart was too flat, a table too dense. We needed a network graph. The problem? Most chart libraries and BI tools don’t support that out of the box. You either say “no” to the feature request, or you hack together a standalone visualization that breaks the product’s flow (no filters, no interactivity, no…
In plain words
Luzmo is a dashboard platform that lets users create custom chart types beyond the standard offerings. Built for analytics teams who need specialized visualizations like network graphs, it allows developers to write custom visualization code that integrates seamlessly with dashboards while maintaining core features like filtering and interactivity. The product handles data querying and management, letting users focus on designing charts that actually represent their data accurately.

In the maker’s words, at launch
Most analytics tools give you 10–15 chart types and call it a day. But what happens when none of them actually represent your data well? We ran into this when building a CRM dashboard. We wanted to show how sales reps connect to open deals: not just totals, but actual relationships. A bar chart was too flat, a table too dense. We needed a network graph. The problem? Most chart libraries and BI tools don’t support that out of the box. You either say “no” to the feature request, or you hack together a standalone visualization that breaks the product’s flow (no filters, no interactivity, no theming). So we built it ourselves, but in a way that still plays nicely with the rest of the dashboard. Luzmo now lets you define your own chart type, write your own visualization code, and then drop it into the dashboard editor like any other chart. Luzmo still handles the boring stuff: querying, filtering, theming, and cross-chart linking. The end result: - Sales reps become nodes in a network graph, with open deals orbiting around them. - Deal size controls node size; win probability controls color. - Everything responds to filters and interacts with other charts out of the box. The tutorial and GitHub repo walk through the whole process: setting up the builder, defining data slots, writing render methods, and packaging it all up for deployment. I’d love to hear from others who’ve solved similar problems: - Have you ever needed a chart type your BI tool didn’t support? - Did you build it yourself, or find a workaround? - How important is native interactivity vs. just embedding a standalone visualization?

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
