This infographic, which cleverly marks itself as incomplete, marks which Doctors have travelled when. At a glance it shows you how far back or how far forward each of the generations of the Doctor have explored.
If you’re a New Who only fan then the results might surprise you. Some Doctors, like the Third, had their travel limited for a long time so don’t make such an impact on the chart. It’s also worth keeping in mind that Classic Who had longer, more complex episodes, and so on a episode-per-episode bias it makes it appear as if the Doctor travelled less often.
