The basic tool, made for non-coders, offers already lots of customisation options.

Datawrapper has everything you can expect for flexible usage and ingestion in your own CMS. It deploys a rich catalogue of templates, including choropleth and symbol maps as well designed interactive tables allowing readers to sort, select and interact with data.

The price for professional users is reasonable. The free version for personal use has limited features (you cannot export the chart as a vector, but only as PNG). However, it is more than suitable for a personal non-commercial blog.  


FREEMIUM – NETWORK MAPPING Data visualisation is not only charts and maps. In the world of connected data, relationships matter. Representing and visualising relationship is not easy, especially if you have a massive amount of data and multiple connections.

In journalism, the case of the Panama Papers leaked is still mentioned as the most prominent example of a graph database built to explore those data: the investigative work took months to execute and some millions dollar invested in coding, analysis and reporting.

However, if you are not working with big data, you might not need a full graph database solution like Neo4j (the best and the most used worldwide). You need more often a simple way to read and organise a table and convert it into a relationship map.

Rhumbl, born from a group of researchers at the MIT, offers a simple tool for making network visualisations, with a free edition and some very affordable premium options.

Visually, the result is simple and easy to navigate online. Rhumbl is developed with the world of academic research in mind, but it works well with more popular topics as well.
