Of course you are all on Facebook, right? So you all gave Zuckerberg permission to Hoover up all your data to sell targeted advertising. In exchange you can post messages and pics to the world and to your friends. Zuckerberg: creating better communication we create we better world. This ideology is under attack one we understand the true business model behind Facebook. Not only making huge profits but through analyzing and combining the data of the users trying to influence our thinking and acting through advertising/information. Book a flight and within minutes your advised to book a car and a hotel at your destination. And it is not only Facebook but Amazon and Google as well. They all live from the use and misuse of your data. After Cambridge analytics Facebook got the full blow, the others are temporarily off the hook. The result is clear: The sole idea of data is under attack: because of privacy advertising manipulation and misuse. There is something fishy about data.

HOW TO ANALYZE: FROM FLOURISH INTO R



Flourish is an awesome tool to create charts. Its output is almost art; this could move data journalism away from its original goal: being a kind of 'sociology done on deadline', aiming at 'improving reporting by using the tools of science'. Although a chart can be made fast, easily and beautiful, the question still is what does it show and what is the meaning?
Below I show how to use R and R Studio to do an analysis of the same dataset.

h<-read.csv("health2.csv")

FLOURISH: DIY DATA JOURNALISM CHARTS

You don't have to be a highly skilled data journalist to create interesting graphs and charts. There are a large number of internet sites were you can drop your data  and retrieve in seconds awesome graphics to embed on your news blog or website. I have been working in my training with for example Datawrapper, Plotly, Tableau. Recently a tweet by Alberto Cairo draw my attention to Flourish. Amazing! Flourish, based on a cooperation with Google Newslab, easily beats the competition. And of course for free. Create an account, login, choose a template and you are in business.
I played around with it, using some data of the Worldbank.  I selected a number of Sub-Sahara countries and download life expectancy and gdp per cap from 2000 to 2014. Here is my creation, done in a few minutes.
