exoplanets.org has an interesting plotting facility. If you’re thinking about the bokeh feature set, it’s worth spending a little time with.
I tried “peer-reviewed orbits by date”. Clicking on one of the data points brings up a table of planets, each of which is a link to the planet’s data sheet (if I can call it that).
It’s odd to think of an astronomical database with less than 1000 data points, and I have no idea what technology they’re using or how it would hold up with, say, a billion elements. But it’s a nice little application, and fun to poke at.
Then again, it might be objective evidence I should get out more…
