How to lie with Charts

Charts, are a regular component of maps. Just like maps, subtle changes can distort the message that the data has. While maps must lie, by distorting space/scale, charts need not. Yet incomprehension, bias and desire to 'jazz-up' charts usually leads to false 'statements'.

The original program on which the publication is based on was written in Java but loving SVG I decided to recreate the model using JavaScript and SVG. I also created a version without SVG using div tags as cells instead for speed comparison testing. Surprisingly, and much to my happiness, using SVG was slightly faster than using the DOM to display square cells.

My work at the University of Luxembourg focuses on developing a residential model utilizing economic theory for agent location. Agents locate depending on many internal (family) and external (environment) factors. An import consideration for any household is a location’s accessibility to public (train station) and private (shopping) services and work. In order to determine the accessibility of a location you must determine the distance, time and/or cost of reaching all desirable locations.
