Had the idea after I needed to visualize some data I had gotten in CSV. Usually I would write some quick Jupyter notebook code or put it in Excel. But writing code is too much work when I just want a couple of charts. And Excel is both frustrating and not powerful enough. I could use something like Tableau but I find it a little overwhelming, and I am wary of handing over my data.
I figured I must not be the only one with the same frustrations and preferences.
At some point I found a post by Jakob (Mac developer of database apps at http://eggerapps.at) where he was looking for something similar. I got in touch with him, and he was quick to validate the idea.
That was it! I had enough to get started.
