Announcing LightningChart JS 8.3: sunburst charts, multithreading, new dashboards

What is LightningChart JS?

LightningChart JS is a data visualization library for building high-end JavaScript charting applications in complex scenarios that demand high-performance data processing.

Introducing the Sunburst Chart

LightningChart JS introduces the sunburst chart, used for displaying hierarchical data as a series of aligned rings. LightningChart JS now makes it easier to explore part-to-whole relationships simultaneously across multiple levels.

Multithreading Performance Optimizations

Just when you thought that LightningChart JS could not get any faster, version 8.3 introduces Multi-threading Performance Optimizations as a built-in functionality to make your charts even snappier.

By using multi-threading, we were able to load an absolutely massive data visualization with 40 channels and 10 million data points each in just above 1 second. And you can zoom in/out/reload data without any lag.
