        <h2>(DW1) Hartnell through (DW11) Smith</h2>

<h3>Time Jumps between 100 and 1000 years - By Episode. Adapted from: <a href="https://www.theguardian.com/news/datablog/2010/aug/20/doctor-who-time-travel-information-is-beautiful">Guardian Data Blog</a>, 2010</h3>
		
		<p>The premise of Doctor Who is that he is a Time Lord, capable of ridiculously epic travels throughout time and space - even if it is billions of years into the past or future and/or numerous time jumps in a single episode / story arc. </p>
		<p></p>
		<p>This dataset represents a fraction of his Earth-based Time Travel. The Time Jumps are the Sum of DateTo and DateFrom per the episode Date references themselves as scripted) ... the glory of Science Fiction!</p>
