On November 20th we had the pleasure to host the 9th MilanoR meeting in Mikamai! Lots of you participated with passion and enthusiasm and we’re so glad of the outcome. Thank you all, from the bottom of our hearts! This time the meeting focused on a thrilling and very useful subject: Data Visualization. This post is thought for you who participated and want to look through the materials again, and for everyone who could not make it.
