I think it is super cool, and it gives me many ideas. I have a similar personal project that I am working on, and I was struggling to find the proper API to retrieve the data, managed to get some from the World Bank, build my own charts with Chart.js etc... Stupid of me to just not rely on the existing data from OurWorldInData.org. The World Bank has very specialized data that might be handy if you work in a specific industry tough (like logistics etc.). I am in the process of reworking on my personal tool and will definitely get inspiration from your work Lars. Thanks.
