I have been able to import historical MER (Monthly Economic Report) data into Tableau. The data was retrieved in CSV format from here: https://www.eveonline.com/news/t/monthly-economic-reports. Would like to thank CCP for making this data public! I created a graph of the velocity of Isk in relation to the money supply.
My next steps is the last part of the data wrangling. I need to import live / real time market data into Tableau.
