As we’ve got with data scraping, the reason data visualisation is often done badly is this is a complex skill, and people pay good money to learn them. So, yes, picking up the basics is good and important. But once you’re going to go beyond novice level, you’re going to need either to spend some money or or hopefully, find someone who’s willing to teach you pro bono.

The consequences of doing data visualisation badly are that you simply don’t get your message across. It doesn’t always have to be as dramatic as the Space Shuttle Challenger. burning up on re entry because the foam pad problem was not well explained a la Edward Tufte. It can be as simple as people reading your blog post, don’t get the point. Because you use a bar chart instead of a pie chart, a bar graph instead of a pie chart where you don’t use anything. You rely on words, when everyone knows that a picture is worth somewhere in the vicinity of 800 to 1200 Words.

The fixes for this are pretty straightforward. Learn some of the basics from people who know better, watch how they do things. Think about how the professionals do it. That doesn’t mean you have to mimic them and build up your skills and have a base repertoire search for the types of information that you are trying to get across. Whether it is how much of a carbon budget is being used up or how long it has been since the council received your freedom of information act or how many of the counsellors on the council belong to one party or how soon it is to the apocalypse.
