Workbench (https://workbenchdata.com/)the data journalism platform with built-in training; a project of Columbia Journalism School will close Oct 15. The project started in 2018 and is offering interesting tools and examples for data journalist. Pierre Conti, Co-founder and CEO writes: “ we did not succeed in creating enough revenue to make Workbench sustainable. Funding for journalism technology is scarce, and we did not manage to attract enough paid users to build a healthy business”. That is a pity of course, but you can build your own workbench running from you own machine. See instructions: https://github.com/CJWorkbench/cjworkbench/wiki/Setting-up-a-development-environment .
