D3.js
D3.js is a data visualization library by Mike Bostock, who is also the primary creator of Protovis, which D3 is designed to replace.
There is a great introductory tutorial available from Luke Franci. It is one of many other tutorials linked to from Bostock's D3 wiki.
The SSH Open Marketplace is maintained and will be further developed by three European Research Infrastructures - DARIAH, CLARIN and CESSDA - and their national partners. It was developed as part of the "Social Sciences and Humanities Open Cloud" SSHOC project, European Union's Horizon 2020 project call H2020-INFRAEOSC-04-2018, grant agreement #823782.
