I find the 'piano roll' visualisation, as used by most major sequencers/DAWs is a much more intuitive way of showing how chords and intervals work, precisely because it is proportionally spaced.
I'm not saying traditional notation isn't useful, I'm saying it's unhelpful if you're trying to understand how music actually works.
