Best Javascript Chart Libraries for 2021

 

Best Javascript Chart Libraries for 2021


-------------------------------------------------------------------------------------------------------------
First and foremost is a library I’ve used frequently in industry and it never fails to please. NVD3 is a library that sits on top of the d3.js JavaScript library utilizing many of the usual traits.
The library doesn’t have every single chart imaginable but has all the most popular core ones. For example, scatter, bar, line. The rendered charts have a very easy-on-the-eye style with pastel-like colours that go well with any dashboard.

Notable Feature List

  • Completely responsive
  • User-friendly tooltips
  • Customizable tooltips
  • Easy to work with JSON
  • Series turn on / turn off
  • Legends
  • Dual-axis capability
  • Quick and easy to download and use
  • Plenty of examples
  • Live chart playground
Licensing - NVD3 is released and licensed with the Apache 2.0 license meaning it’s completely free to use for both personal and commercial practices.
Links - NVD3 is hosted on various CDN networks as listed below

2. Dygraphs

Dygraphs is probably one of the fastest rendering charts I have come across, especially when the data set is vast. This library can handle data sets going into the tens of thousands and still deliver a great user experience.

Notable Feature List

  • Can handle huge data sets and is superior in this department when compared to other libraries
  • Cross chart synchronization
  • Annotations, and highly customizable annotations at that
  • Range/Viewfinder
  • Very simple to get develop with
  • Perfect for real-time data visualization
  • Extremely fast data point feedback with off-chart data display
  • Zoom in and out functionality
  • Plenty of examples with links to JSFiddles
  • Easy to work with data, simple arrays, or load from text or CSV files
The one drawback to all this glory is that it’s completely based on line graphs. No bars, pies, or anything that you would usually see in a JavaScript charting library. Not to worry though, it’s still an epic package, and here’s why.
Licensing - 

Dygraphs is licensed under the MIT License which offers usage, modification, and distribution by both personal and commercial parties.

Vis.js is a very versatile parent library of other sub-libraries including networking, timeline, 2d, and 3d visualization capabilities. This library offers 3d charts which are pretty rare amongst most charting libraries which definitely gives it an edge.

Notable Feature List

  • 3D Charts
  • 2D Charts
  • Multi-chart capability
  • Optional tooltips
  • 3D interactivity on relevant charts
  • Chart playgrounds demonstrating many of its features
  • Flawless animations
Vis.js has some stunning visualizations in both 2d and 3d forms but of course, all will serve specific purposes. Personally, I’ve never come across the need to use 3d charts but if your working in some type of scientific data analysis background, I could imagine it would be useful.
Licensing - The Viz.js library is dual-licensed under both Apache 2.0 and MIT licenses. Both of these licenses enable usage, modification, and distribution by both personal and commercial parties.

Somehow, the creator of ChartJS got the default colors absolutely perfect and they go so well within any website. It’s again another library that doesn’t have a massive selection of charts but does it very well with the ones it does offer.
