Hi all,

I wonder about creating interval notation using `Intervals`

package, if there is any package that is able do tell me.

I try it this way:

```
using Plots, LaTeXStrings, Intervals
a = Interval{Closed, Closed}(1, 10)
plot(a)
```

But it returns unsuccessfully:

**Cannot convert Interval{Int64, Closed, Closed} to series data for plotting**

The goal is to create a simple interval notation for open and closed set / interval like this:
