The Best Web-based Data Visualisation Tools

Firstly a disclaimer: I am the founder of Dataseed — an interactive data visualisation platform. I’ve spent a lot of time reviewing the various data visualisation tools on the market and so these are really my personal favourites. I first put together this list as part of a talk I gave at the University of Westminster in 2016 and I’ll aim to keep it up to date.

There is a focus on the more affordable, cloud-based and open products, avoiding the BI monoliths and the niche industry-specific tools. All of these tools are cloud-based and require no coding to use. This selection should be particularly useful for data journalists, analysts, developers and even the causal non-coding user who wants to step up their Excel game.

Criteria

In order to assess which tool is best for our purposes, we need to know something about the ways in which they differ. I’d advise against creating a hideous granular matrix to evaluate features. Instead just narrow down what you’re looking for and then try some tools out. I suggest this as a decent enough high-level framework for classifying data visualisation tools.

Who is the Target Market

What is the Pricing Model

Technical Architecture & Scalability

Customisability

Type of visualisations

You really need to have some idea of what visualisations you want to create. Tools tend to specialise. A decent framework for thinking about the available options would be Stephen Few’s 8 quantitative messages:

I would also add one to Few’s list — Relationships. Often thought of as graphs / networks.

Key Functionality

The products

In roughly ascending order of complexity.

Datawrapper — Best for simple single charts

Perfect for quick, single charts to be embedded within your website / blog. Can only handle small amounts of data, but very easy to paste in data from a spreadsheet, choose your chart and modify it’s appearance within the UI.

Target Market — Journalists, blogger.

Pricing — Free to start, €12/m to embed, €129/m — €499/m team plans

Tech Architecture — All data and rendering in-browser, so limited volume.

Customisability — Very good — open source means that you can fully edit the code to customise the charts if you want to.

Visualisation Functionality — Single charts only. Can do all common charts (line, bar, stacked bar, donut, table) and a few less common ones. Choropleth is the only type of map supported.

Plotly — Best for complex / scientific charts

Supremely customisable single charts and static dashboards that can be created through the UI. Ideal for producing complex scientific plots, it has connectors for common data analysis software such as R, Python, MATLAB.

Tech Architecture — All data and rendering in-browser, WebGL and SVG.

Customisability — Very good, open source & API.

Visualisation Functionality — Single charts only, or dashboards that are essentially just multiple charts on a page — no filtering. Really comprehensive collection of charts to work with.

Dataseed — Best for interactive dashboards

Interactive dashboards and data exploration. Simple drag and drop UI to create visualisations. Modern, lightweight platform that can be embedded in other apps.

Customisability — Good enough for most, but not open source.

Visualisation Functionality — Static dashboards, where the charts are not clickable. Most common charts including choropleth maps.

This list is obviously not comprehensive, there are many more web-based data visualization products on the market. It does however represent my personal favourites in each category, the tools I turn to when I need to get something done, fast.

If you’re looking for something a bit different to these tools then our team at Atchai creates bespoke data driven applications incorporating machine learning, data visualisation and all the good stuff. I’d be happy to chat through your project, just send me a mail.
