Alright, so this might be a little bit abstract (or maybe completely obvious?), but it would be interesting to get an opinion nonetheless.

Questions:

- Does it make any sense to plot this?
- if question 1 == TRUE, how would I go about it? What am I looking for?

Let's say I have two one-dimensional data frames.

```
df1 <- data.frame(a = 0, b = 0, c = 1, d = 1)
df2 <- data.frame(a = 0, b = 1, c = 1, d = 0)
```

In words (since I have no idea how to do this):

I'd like to visualise how each value in df 1matches the values in df2, and vice versa. E.g. if df1["a"] == df2["a"] add something to the plot. If they are unequal, add something else that displays if either df1 or df2 was 1 or 0.

My initial thought was something in the lines of a geom_point() plot using the size argument for matches, but I guess that would just cluster the values at 0 and 1, unless I'm able to somehow set the x and y axes to a, b, c and d?

Thank you!
