During the redesign of its model, the weekly Marianne asked us to lay the foundations of a data visualization charter and to design, for the editorial designers, a Data Viz kit. The objective being to enable them to quickly format the data collected by journalists, in a clear, harmonious and coherent manner, from one model to another, all in the spirit of the graphic charter established by the newspaper. The result is around forty charted models, available according to the colors of the sections, accompanied by a chart of pictograms to illuminate the new version of the weekly, offline and online.
