Rawgraphsrecommended by the médialab

Rawgraphs is an online tool allowing to build visualizations from tabular data (.csv, excel, framacalc, google spreadsheets,...).

The tool allows to very easily scaffold visualizations using often complex techniques (e.g. bubble charts, alluvial diagrams), then to download them as publication-ready images or .svg files which can be reworked with vectorial images editing software such as Inkscape.
