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.
