MoM 2020 Week38 – Tableau
This line chart I created shows that it’s around 2014 when books stopped getting more expensive than other products. We can see a clear trend of both books and other products’ index, but this visual poses a question, “Do Books include electronic books or only paper books?”. This is why data visualizations (good ones) are great in that they not only give you answers to your questions but also pose more questions you might have not thought of.
