Some Pies and Bars

 As in the past years the ABSOLAR continues to produce their charts with some limited methodology on data visualisation. This becomes obvious when we look at the mixture of pie charts and bar charts. The chart "Matriz Eletrica Brasileira" is of the same type - structural single year chart - but presented in a different way, as for example "Geracao Distribuida - Ranking Estadual" which comes as a bar chart and can be read much easier. Simplifying, unifying and structuring the charts could be more helpful for the reader.

How much does my small solar power plant produce?

 Different views of solar power production. Standard modules of browser presentation. Background color and scaling are in my opinion main deficits of presentation.

Climate - Emissions - (In-)Equality

 Oxfam recently published a report on climate equality. Climate change seems to be a serious socio-economic problem. But will the winners pay the bill?









Most of the report data is based on the data collections of the Stockholm Environment Institute and the Emissions Inequality Calculator.












Emission data on a world wide level is provided by climatewatch.org

Charts und Infographs



Spaghetti-Charts sind wirklich nur schwer zu durchschauen




Es könnte auch heißen: Mehr als die Hälfte aller Erhaltenden sind Migranten. 
Die große Herausforderung dabei ist es, Frauen über 30 Jahre in Lohn und Brot zu bringen.



Das ändert aber nichts an der Tatsache, daß die Grafik u.a. als Strukturgrafik dargestellt werden sollte und die Labels direkt und differenzierter in der Grafik angebracht werden könnten.




Aber: Wenn die PV-Anlage auf dem Dach ausreichend speicherbare Energie produziert kommt es auf die Dämmung auch nicht mehr so an....
