Hello KNIMErs,
Here is my solution to #justknimeit-7 :
KNIME Hub > gonhaddock > Spaces > Just_KNIME_It > Just KNIME It _ Challenge 007
Task (1) - in this opportunity as I’m not used to work with JSON files, and aiming to learn further; I’ve decided to retrieve the latest data from UN ‘unstats.un.org’ statistical Server. Now I know how to query it in both R and Knime 
.
Task (2) - I just downloaded from the web a copy for the ISO 3166 COUNTRY CODES, that already addresses Region and Sub-Region, ISO codes…
Task (3) - I’ve mixed up interactive charts with R histograms and maps, these latest unfortunately aren’t interactive at the moment.
BR
PS.- Does someone knows how to custom / color component nodes?
