After spending some time on the World Bank website, it demonstrates a good range of data in relevant areas for this project, and also has a tool for creating data visualisations using the data provided. It has a relatively simple interface, but does not seem to be intelligent enough to suggest specifics for creating more readable data visualisations.
I will play around with this tool and see if I can create some usable data visualisations for the final piece of data journalism.
I have noticed that you can select as many variables as you like, which isn’t ideal, as it then creates unreadable or confusing data visualisations. Above all I want my data visualisations to be easily readable, or they fail at the most basic level.
