• Conclusion

In today’s world, people are struggling more and more with the problem of scattered attention. So it is highly important to present information in a structured and well-designed way; especially if you have a complex business application. Presenting huge chunks of data in a standard spreadsheet to analyze or to study is as inconvenient as it can get. Creating different charts is a big issue that we will consider.

Javascript charts are an essential part of a web application for presenting data. It means JavaScript charting libraries are inevitable. The way the human brain itself is programmed is that it understands visual data much better than anything else. Well visualized data creates much more influence than the data being presented as it is, no matter how well it is explained.

Companies build strategies around the charts, numbers, and tables they’re presented with, and often use them to choose whether to pursue business opportunities. It is very important to choose the right tool to build a workaround.

But how do you choose the tool that will fit your requirements in the javascript technology zoo? How to choose the right graphics for your data? Should it be paid or free? Build your own solution or take a ready-made tool?

We will try to cover all these questions in this guide. First, we will talk about how to choose the right javascript charting library. Then we will define the criteria for evaluating the tools, and finally, compare the most popular javascript charts on the market.

How to choose the right javascript charting library?

When you approach the choice of the chart js library, everything is highly individual and depends on many criteria. Therefore, in this section, we will consider things you should pay attention to while choosing the tools for drawing charts.

There are quite a few javascript charting libraries around now, but which are the best to use? This can depend on many factors like business needs, types of data, the purpose of the chart itself and many more.

A nice interface and copy/paste code are all well and good if we need something generic to our needs. But frankly speaking, most of the time we actually need something tailored to our use case. Even more than that  –  we need a reliable charting library we could build upon.

There are several factors to consider here:

• What kind of charts does the company want to build? Pie charts, maps, lines, bars?
• How large is the dataset?
• Is the app going to be used for Web, mobile, or both?
• SVG or Canvas base?
• Libraries based on SVG are usually better for smaller to medium datasets, as each element is a unique node and exists in the DOM tree. On the other side, Canvas is really fast.
• What is the browser support for a given library? Check your browser market share to figure this out.
• Which JavaScript framework do you use?
• What kind of customization of the look and feel do you need?

Note that in some cases you may not need a data visualization library at all. Sometimes it’s better just to write one from scratch using vanilla JavaScript.

Here is an example of a decision diagram that I have found on the internet. 

Top JavaScript chart libraries

In this article, each JavaScript charting library will be compared with some key factors including chart types, commercial or free, and open-source status. These beautiful libraries have been analyzed thoroughly with hands-on experience to maximize the very best comparison.

Highcharts

License: Free for non-commercial, paid for commercial
Price: Free to $7060
Main dependencies: No dependencies
Web-site: https://www.highcharts.com/

HighCharts a modern javascript charting library based on SVG technology. It doesn’t require any plugin. The integration with all of the major web frameworks is very simple.

In all of its simplicity, Highcharts is also very much compatible with old browsers, so you can pick it if you don’t need to represent data using advanced charting styles.

Notable Features:

• Optimized for both responsive design and touch devices;
• Capable of working with Big Data;
• On-hover tooltips rendering is super-quick;
• Ability to annotate graphs;
• Data can be loaded to charts directly from a CSV file.

Highcharts allows you to configure the theme separately from the data. This allows you to have a common theme for your brand to apply across all the charts on your website. 

Highcharts is extensively documented and has most use cases covered. 

HighCharts is used by some major companies across the world, including Facebook, IBM, MasterCard, and StackOverflow. It’s probably the most advanced library out there regarding types of charts available, but of course, comes at a cost for commercial use. If the pricing is not a stumble, Highcharts is an excellent choice.

Chartist-js

License: Open-source
Price: Free
Main dependencies: No dependencies
Web-site: http://gionkunz.github.io/chartist-js

Chartist is a very modern, SVG-based library. Its biggest feature is the SVG animations in the charts produced with this library.

It has a solid technology base and is very easy to implement. Within minutes you can make an incredibly impressive chart that interacts easily with any backend data source. Chartist is really easy to configure, as well as easy to customize with Sass.

This library has only 8 base chart types which can be used to improvise over a few more different types. Each is fully responsive but doesn’t have a great transitional effect as others.

Features:

• Filtering by labels; Click on a legend to show and hide data on the chart;
• Non-numeric Y-Axis, have labels instead;
• Easy customization with interpolation of line charts.

The Chart.js visualization library is completely open-sourced with the MIT License and available to modify, distribute, and use. Source files are available to ‘fork’ on GitHub too.

Chart.js offers a vast documentation base including precise instructions on installing the library. The library can be quickly installed with Bower, NPM, jsDelivr, and can even be linked up from CDNJS. Besides, you can download the source files directly from the GitHub Repo.

Chartist is a very powerful charting library, but it requires more work on the developer’s end to get things to look right.

Recharts

License: MIT
Price: Free
Main dependencies: d3.js
Web-site: http://recharts.org/en-US/

Recharts provides a set of modular javascript charting components and does a great job by letting you mix those components together to easily build things like a composed line and bar chart.

It is the most popular library to date. It has more than 11k stars on Github, but there is a huge number (600 to date) of open issues as well.

The documentation is quite extensive but lacks details in some parts. You can find a bunch of examples at Recharts website, which could be a good starting point for building your own charts.

What’s a bit troubling is the high number of unsolved issues on GitHub. These issues may not be critical, but creators don’t seem to drop by to answer them too often. So if you get stuck, be prepared to dig deep into the library.

Conclusion

With charting being something we all need to implement so often now, it’s no great surprise that there are many open-source charting libraries available for us to choose from.

All of the javascript charting libraries we mentioned above have very good browser compatibility and fallbacks available for people using legacy browsers. The libraries built upon D3 have a solid base, but personally, I find them a little bit underwhelming from an aesthetic aspect.

Javascript chart Libraries like FusionCharts, GoogleCharts, Dygraphs, or one of the D3 derivatives may work best for corporations with large data sets, or small businesses that rely heavily on data analysis. Both commercial offerings, Highcharts, and FusionCharts are mature libraries that can fit most use cases very well. Both of them have varying degrees of support for large datasets (>100k data points) and support a large variety of charts. If there is a specific type of chart you need to render, the choice might narrow down to only one of them.

If you just need something small and quick, Morris.js or Chart.js might work better for you. For graphs and networks, Cytoscape or Sigma.js is probably the way to go.

If you want to stick to a free and open-source library, use Chart.js. It is extremely simple to use for common use cases. If you need a little more control over rendering, then you could look into Chartist.

P.S. We have prepared a table to show the popularity of libraries by downloading them through npm. We see that the most popular are d3, chart.js, and Highcharts.

Conclusion

To select the best JS chart solution for your unique needs, I recommend testing your own data against a couple of the libraries listed above to ensure a perfect fit for your current and future projects.
