EL ESPAÑOL data unit doesn't create every graphic published on the newspaper. We are happy leaving the job of making simple charts to the rest of the newsroom.
Datawrapper is a tool that just does that, it allows non-coders to create graphics on a web interface. I installed and customized the app on a server, creating a unique stylesheet for the charts based on a design guideline.
To the date it has been widely adopted by the journalists, counting 800 charts since October (200 per month!).
Tools: Apache, PHP and CSS.
