Good read about 10 years looking back from Mike Bostock, BDFL of D3.js lib: https://observablehq.com/@mbostock/10-years-of-open-source-visualization Nice words. Take aways: - examples, examples, documentation (read: pyqgis and more more QGIS-tutorials online) - stay kind and polite to each other Regards, Richard Duivenvoorde
