You may have encountered the “Warming Stripes” from Ed Hawkins, a beautiful and brilliantly simple visualization of global warming.
I like the purity of the charts, which comes from the absence of labels or
scales. However, this leaves the reader with unanswered
questions, such as “what is the range of the warming?” or “when did the
warming become so obvious?”
Therefore, I decided to reproduce the visualizations using Bokeh and HoloViews. These interactive plots allow to glide your mouse over the chart and read the values associated with each color:

With the interactivity, more complex plots become possible. Here for example with monthly anomalies instead of annual values:

Feel free to embed these plots wherever you want!
