Vincent Warmerdam shared his new tool to quickly simulate artificial datasets: www.drawdata.xyz.

Happy to announce v1 of a hobby project. It's a tool that allows you to draw and then download a dataset. https://t.co/oPYVesUTBU pic.twitter.com/kSMZoIsaYL

The drawdata.xyz tool allows you to easily create your own line- and scatter-plot with different groups of datapoints following specific x-y patterns.

After drawing your data, you can just click to export your new dataset to csv or json format.
