<li>Data values are visualized using color AND as locations of points on a graph.</li>
<li>The average temperature in reference period 1951-1980 determines boundary between blue and red.</li>
<li>Horizontal scale is time, from 1850 (left) to 2018 (right).</li>
<li>Each hue (up to 8 blue and 8 red) covers a temperature range of 0.1 degrees Celsius.</li>
<li>Data is global (not for a locality).</li>
<li>A similar (composite/overlay) graphic was retweeted by Ed Hawkins (<a rel="nofollow" class="external text" href="https://twitter.com/ed_hawkins/status/1018879666910826496/photo/1">here, July 16, 2018</a>).</li></ul>
