Housing market● Many options to visualize
instead of bar-plots and donut/pie plots.
● Example of visualizing houses being sold in various areas of the Netherlands○ 4 largest cities○ Market shrinkage areas○ Remainder

Housing market
● Scaling matters
Housing market: Moving behaviour
Safety: social tension indicator
− Use social media to detect feelings of tension and unrest on a daily basis.
