Best Chart Libraries for 2017

We recently did a roundup of the best online spreadsheet software for 2017, but while spreadsheets are undeniably great for managing data, they are rather limited when it comes to visualising data. You could turn to Power View in Excel, but why not look instead at the many fantastic chart libraries that are available? They are highly customisable, include animations (if that’s your thing), and in most cases can output charts that your audience can interact with. So get ready to say goodbye to flat, static data visualisations with our roundup of the best chart libraries of 2017.

Datawrapper

Datawrapper’s primary audience is journalists and newsrooms, and it is built and supported by a dedicated team of engineers, journalists and designers. Since launching in 2012, Datawrapper has grown to count The Washington Post, The Wall Street Journal, Le Monde, and other top publications as clients. Their pride has always been in giving users the ability to create interactive charts and maps in minutes.

This line chart shows in a simple and understandable way results from COD game.

A feature-limited demo version is available, with full versions priced from 19€ /mo to more than 499€ /mo.

Highcharts

Highcharts began as a side-project for Torstein Hønsi , who wanted to include a simple chart of snow depth measurements on his homepage. Highcharts was ready to be publicly launched by 2009, and is now considered a premier charting-tool. Not just in Norway, but across the world, with 97% of revenue generated from customers outside of Norway.

This line chart illustrates the interactivity of Highcharts, which helps keep your chart uncluttered without reducing any value.

The backend of this analytics and data visualisation tool uses Python and Django, but the front-end is Javascript, with visualisations rendered using D3.js, HTML and CSS.

Plotly’s interactive chart reveals information in relation to where your cursor is positioned, not only when hovering directly over a segment.

The aim of the developers is to keep Chart.js as a simple yet flexible chart solution for designers and developers.

Like amCharts, this demo using Chart.js allows you to display a lot more information when hovering over each segment, not just values.

ZingChart

ZingChart started out as a solution to a problem being experienced by Thomas Powell, with the first version of ZingChart launched in 2009. The goal has always been to have a flexible and fast product that makes use of modern technologies, and can be used anywhere.

This ZingChart shows how your charts can be dynamic even without any interactivity. The animation used loads the chart in steps, rather than a fluid reveal.

Pricing

Free version available using a branded license. Commercial licenses, with no branding, are available from $199.

Key Features

Conclusion

Chart libraries are a visual tool, and as such should be evaluated on the quality and usefulness of the visualisations they render in relation to your need. However, they are not the only feature you should be evaluating. Support, integrations and overall stability are just as important, but no matter what libraries any roundup list, the overall winner is always the one that meets your specific needs.
