d3.js radar chart

Nadieh Bremer is the maker of the radar chart that I am going to use. The opinions about the usefulness of these type of charts are divided. She started redesigning her old radar chart to make the new one that I am going to use for my project. A radar chart is also a graphical method of displaying multivariate data in the form of a two dimensional chart or more. Typically, radar charts are generated in a multi-plot format with many stars on each page and each star is representing one observation.

Why I choose the radar chart

After finishing my concept I needed a chart that could show observations of the data that I wanted to show. When I was searching in the D3 examples I had picked out a few charts that I could possibly use with the concept that I had. In the end I picked out the Radar chart. This was because I thought it looked interesting and the d3 code that is used for this chart did not look too difficult.

Final results

After I plotted my code into the radar chart it did not look what I was expecting at all. It doesn't give a good overview of all the continents and how much % every main categories have in these continents. Because the time of cleaning my code and getting the perfect structure for this chart took way to long because I needed to get data from different queries and work with promises. But I started to work on D3 one day before the deadline and used a library that was already made and I did not change anything about it and only uploaded my data into it. I read a couple articles of d3 but nothing big at all. So the d3 of this course is minimal if you compare it with what I did for cleaning my data. I think I miss understood the purpose of this course.

This is the data visualization if I load in my code.
