present jupyter notebooks (e.g. for data upload) executable online

[tillmo]

this is possible e.g. with binder, see also e.g. here Note that a jupyter notebook has an upload button on the top right, so you can upload data into the binder virtual machine, and from there via python in the notebook to the oep.

From a chat I got: The JupyterLab interface even allows drag-and-drop upload. That first section here tells you how to switch interfaces on typical MyBinder-launched sessions. In JupyterLab, the file browser is in a pane on the left side. You can click on and drag a file from your local computer to the pane and a gray dashed line will light up indicating you are ready to release your mouse to drop it in.
