Gnuplot interface is a little dated, so custom visualisations are not so easy yet many disciplines today have a bunch of them. This should not have been a problem but it is because the gnuplot licence makes it unforkable and that discourages contributions. Contributions -- that would allow it to evolve, e.g into a base package (API) onto which other plotting packages could be built. I think this would be an irresistible allure since gnuplot is in my experience the fastest plotting package out there.
