To sustain user attention and drive audience engagement, journalists and news organizations should learn to use data visualizations.

Data visualizations let you explain a set of data simply with an infographic, an interactive application or a chart.

Leading media organizations are using Datawrapper, a simple and free tool, to improve their storytelling.
