Draw a bar chart about the distribution of Nationality and the sum of ID , and group by attribute Nationality, and could you list in descending by the names?
SELECT Nationality, SUM(ID) FROM swimmer GROUP BY Nationality ORDER BY Nationality DESC
SELECT "Nationality", SUM("ID") FROM "swimmer" GROUP BY "Nationality" ORDER BY "Nationality" DESC NULLS LAST
