We could put the adjustment of ‘N’ and ‘ES’ into 2d slider bar where ‘N’ is on the x-axis and ‘ES’ is on the y-axis; then, we will only have to click once to select both variables. We could also shadow the zone that does not make sense to select since it would not change the main visualization. We could have more than one circle placing side by side, in case the users want to compare how many numbers could be represented between different ‘N’.
Note that the "shadow" comment doesn't actually make sense; all es values are valid. See #31.
