Since 2012 Lanacion.com keeps an open data catalog, with updated datasets. Besides, we report stories with open data published in Google Spreadsheets .
Most of these datasets are manually updated and we use Tableau Public to illustrate most of our stories with interactives as we cannot afford to have developers, we have only one.
Since 2013 our dataviz designer learned D3.js and javascript to develop our own visualizations and we detected many reusable ones that could serve as useful context information for many stories.
