It started with one of my colleague who managed a Tableau case from our end. His client was constantly dissatisfied: her workbooks were significantly faster with embedded data sources compared to published ones. Even if we told her that this is normal, this is the way how life works, so better accept it and let […]

But what if some of our colleagues or clients are still not upgraded to the latest Tableau Desktop version? How can we share our superb new workbook? XML Hacking? Jeff’s converter tool? Forget all.

No doubt that chess is one of my favourite game. It’s more than 15 centuries old but still fresh and enjoyable. Also no doubt that my favourite data visualization tool is Tableau so why not mix these two together?
