It isn't hard to come up with a representation, based on previous work in https://github.com/prometheus/proposals/blob/main/proposals/2024-01-29_native_histograms_text_format.md .

Results are (expectedly) impressive: https://github.com/prometheus/prometheus/pull/17293

One observation is that buckets are a bit dense (readability). However we don't have spaces in any other place (e.g. labels)

This looks good to me overall. I think we can save float histograms for a follow-up.
