There is hardly any person on the planet, who hasn’t probably heard about the 3.7 million people marching in Paris in solidarity to raise red flags on terrorism and freedom of press, following the Charlie Hebdo events. The crowds have been led by 47 world leaders (alternate source) marching arm-in-arm. However, a lot of controversy (1,2,3,4,5,6) has arisen around their intentions and people, bloggers and prominent figures of many countries have questioned whether their leaders’ actions reflect their nation’s viewpoint on this divisive matter. While some leaders have not been welcome, others have been reproofed for not showing up.

In this post we will try to look behind the curtain and see what could be the possible motivators for the world leaders to join the Marche Republicaine!

Charlie Hebdo March Leaders Map

Countries represented at the Charlie Hebdo March, Paris, 2015

We can see that Europe was well-represented, with virtually leaders of all EU countries appearing at the Champs Elysees. Other regions to have a good representation are Canada and the United States (although the US did not send the highest ranking officials), French Africa and the Gulf countries, to some extent – despite the fact that these are mostly Muslim majority countries. We can immediately see from the map that geographic proximity definitely influenced the solidarity visits, but let us look whether the religious majority of a country had any significant effect on the country’s appearance at the march!

This post is an update on the Colorful Development: RGB-coded Multidimensional HDI post. But this time I’m bringing you dynamic plots spanning over the 1980-2013 period, giving us a much more comprehensive picture than a simple world (chloropleth) map about how did human development change in the past 3 decades! In particular, we will look at the evolution of the inequality between the three components (Health, Education, Income) of the Human Development Index. For this, we will need to use tripolar RGBHDI plots (I also call it a colorwheel), a rather peculiar 3 dimensional coordinate system defined in the previous post , so make sure you take a look first.
