A prototype of a visualization system to exploit data on the population ageing in Italian urban contexts

Abstract

There is a strong request to improve the easy of interpretation of the official statistic information. The request is backed by a number of international organizations and is intended to the advantage of decision makers, as well as researchers and non-specialist users. Modern tool for graphical and geographical data visualization offer resources to implement systems suited for the scope. The aim of this work is to perform a comparative analysis between different technological platforms, and to find an effective trade-off between the completeness of the traditional, official statistics and the immediate awareness of a phenomenon given by the graphical and geographical data visualization technologies. The study is performed using two dashboard prototypes implemented with two benchmark platforms: Tableau and ArcGIS Dashboards. Prototypes consist of the very same graphical objects and share a similar layout, however showing a different look and feel, and cover complementary aspects of the statistic information. Both have been extensively tested and proved effective in giving an immediate and consistent comprehension of the phenomenon on study.
