While reviewing [this](https://codereview.stackexchange.com/q/86879/52915) piece of work I found out I need a file with a specific format. I don't happen to have those laying around and I wouldn't know where to get one either.

I'm looking for a `.shp` file, content doesn't matter. Attributes should be:

```
ID
IDsub
ValueSum

```

What kind of data is this and where do I get a file to test the code on?
