What is the commonality? April ... Echternach Vianden Diekirch Grevenmacher Clervaux Wiltz Mersch Remich Redange Luxembourg Capellen Esch
What is the commonality? April ... – Simple scatterplots... – ... but elements have no pre-defined location on the canvas – Key to the drawing is calculating the plotting positions!
Examples Principles and mechanics Implementation
Force-directed layouts – Element positions determined by a stochastic simulation algorithm – Elements “interact” with each other in order to find their position on the canvas – Interactions through combinations of few simple forces: » Gravitational forces (positive or negative; attractions or repulsion) » Spring forces (towards target distances) » Collisions – Start from random positions and iterate until convergence to a stable plot – Stochastic: randomness in the resulting plot (set your s❡❡❞ )!

Different combination of forces lead to different types of plots Attraction forces between points and Spring forces to target connected node towards ‘anchors’ (hives) + collisions distances and repulsion April ...
