Se le nota en la voz, por dentro es de colores (Si te vas, Extremoduro) This is a gif generated with 25 plots of the Fermat’s spiral, a parabolic curve generated through the next expression: where is the radius, is the polar angle and is simply a compress constant. Fermat ...

You cannot find peace by avoiding life (Virginia Woolf) Combining polar coordinates, RColorBrewer palettes, ggplot2 and a simple trigonometric function to define the width of the tiles is easy to produce nice circular plots like these: Do you want to try? Here you have the code:

Heaven we hope is just up the road (Atlas, Coldplay) Following with the analysis of migration flows, I have done next two visualizations.

Do not swear by the moon, for she changes constantly. Then your love would also change (William Shakespeare, Romeo and Juliet) The sun is a big point ant the moon is a cardioid: Here you have the code. It is a simple example of how to use ggplot:

Triangles are my favorite shape, three points where two lines meet (Tessellate, Alt-J) Inspired by recurrence plots and by the Gauss error function, I have done the following plots. The first one represents the recurrence plot of where distance between points is measured by Gauss error function: This one is ...

Every finite game has an equilibrium point (John Nash, Non-Cooperative Games, 1950) I read recently this amazing book, where I discovered that we (humans) are not capable of generating random sequences of numbers by ourselves when we play lottery. John Haigh demonstrates this fact analyzing a sample of 282 raffles of 6/49 UK ...
