Plot regional data from by-country indicators?

GROUPS:
 Hi,I have a csv containing columns for countries, indicator name (e.g. population, fertility), and several columns for values on different years, such as a column for 1960, another for 1961, etc.How do I create a listplot for regional data (grouping countries) taking the indicator of each country, calculculating a weighted average by population.Below the exampleAny help would be highly appreciated as my table is huge and have to create dozens of similar charts. s = Import[ "C:\\Users\\Jesus Enrique\\Documents\\Wolfram \ Desktop\\Sample1.csv"];  Attachments:
 Hi Enrique,you can begin in a very straightforward manner like so: data0 = Import["sample1.csv", "CSV"]; years = DateObject[{#}] & /@ data0[[1, -4 ;;]]; data1 = Association[#1[[1]] -> <|#1[[2]] -> <|Thread[Rule[years, #1[[3 ;;]]]]|>, #2[[2]] -> <|Thread[Rule[years, #2[[3 ;;]]]]|>|> & @@@ Partition[Rest[data0], 2]]; ds = Dataset[data1]; In this nice form of a Dataset one has a very direct access to every single element, e.g.: yr = Key@*DateObject@*List; ds["Algeria", "Population", yr@1961] and the overall picture can be made visible easily, e.g.As for a start I hope that helps, regards -- Henrik
