3D scatter plot showing UK schools values for teacher headcount, number of pupils on free meal and IDACI score.

This weekend I wanted to learn a little bit more about Plotly Dash. I wanted to build something quickly with the idea of using real-world data.

So, I come up with a simple cluster analysis of some of the best data sets openly available on the Web: UK schools performances.

This datasets it’s a gold mine of information about schools in UK including:

I also wanted to join this data set with the UK Deprivation Index to show potential correlations between the economics…

I decided to learn Python a little bit more and I needed some data to perform a simple exploratory analysis to practice a bit with Pandas data frames & co.

So I came up with a collection of 79764 tweets collected between 2017–05–09 15:47:36 and 2017–05–19 geo localised within the London bounding box:

{ p1: [-0.489, 51.28] p2: [0.236, 51.686]}

To collect them, I just used a simple Scala/Play app that listens to all geo tagged tweets within a particular area and stores them in a relational db.

The code is open source and can be found here.

Let’s group…

on real purchasing power across Europe

Inspired by this map about the real value of 100$ in US, I decided to bring back some of R reminiscences and to do a similar exercise for Europe (formally: the 28 EU Member States, 3 member states of the EFTA, five candidate countries and one Western Balkan country).

What are the purchasing power differences within some European countries?

The real value of 100 € in each country in 2015

The values have been computed adjusting the value of 100 € to the Purchasing power parities (PPPs) indexes for each mapped country.

PPPs are indicators of price level differences across countries. …
