There are lots of data at OECD.Stat. Unfortunately, they are not available in the JSON-stat format. But they are available in the SDMX-JSON format.
JJUS includes fromSDMX() that converts SDMX-JSON (flat favor) to JSON-stat. Warning: JJUS version 0 fromSDMX does not support Internet Explorer: you need to provide a polyfill for reduce, find and findIndex.
Once the JSON is converted, it is processed using JJT and the data is visualized with ChartJS.
