Thanks Alexandre, even more being away of the computer... It kind of
works. Now the visualization shows the labels in the upper side of
each rectangle. Like this:
The idea is to put labels like "uno", "dos", "tres", "cuatro",
"cinco" on each rectagle instead of the numbers. Anyway we have
ended our hackathon/workshop in the #DataWeek3 and #OpenDataDay for
today. A really good balance�� and this third edition is the best of
all until now. Still there is a step learning curve and "cultural
shock" on Smalltalk, but agile visualization, the Roassal
environment, GT Tools, and Pharo are promising and interesting for
newcomers.
