Consider a visualization that explores the art pieces hammered during last 10 years by an auction company. The features of artworks to consider for the visualization are:
- the date of the auction
- the final hammer price
- the gap between the minimum and the maximum initial estimated sale price
- if the hammer price is lower than the minimum estimate or larger than the maximum estimate
- the city and season of the auction.
You are asked to:
- draw on paper your personal (non-standard) visualization;
- sketch the drawn visualization in Processing;
- see the visualization depicted by Giorgia Lupi for La Lettura (Corriere della Sera).
