Stephen King Screen Adaptations (Plotly)

Stephen King is a prolific author, whose books I've enjoyed reading since I was a teenager. His prodigious written output has spawned many screen adaptations for film and television, but in many cases I've been disappointed by the screen versions; see, for example, the dreadful "Under the Dome" TV mini-series.

I decided to look at how well-received King's films have been compared with his books. I found a list of screen adaptations, and for each looked up the book's rating on Goodreads and the movie's rating on IMDb. I necessarily omitted screenplays, movie sequels (not a adapted from a King book) and short stories that contributed to only a portion of a movie. I then imported this data into Plotly and produced the chart shown below
Mouse over a glyph to display details.

The chart reveals a positive correlation between the ratings of King's books and their screen adaptations. Highly rated novels such as "The Green Mile", "Rita Hayworth & The Shawshank Redemption" and "The Body" produced well-regarded movies, whereas poorly rated stories such as "Trucks", "The Mangler" and "Tommyknockers" resulted in absolute stinkers on screen.

We can also see that TV adaptations (wide glyphs) were generally less well-received than were film adaptations (tall glyphs). So too short stories (orange glyphs) and their screen adaptations tend not to rate as highly as novels (blue glyphs) and novellas (green glyphs), and their screen adaptations.

Incidentally, this was my first time using Plotly. I was able to import my data and generate a scatter plot with relative ease. Customising it for my needs took a little longer as I was new to the tool. I'll definitely use Plotly again.
