CREATE TABLE country (Country_id NUMBER, Country_name CLOB, Capital CLOB, Official_native_language CLOB)
CREATE TABLE match_season (Season FLOAT, Player CLOB, Position CLOB, Country NUMBER, Team NUMBER, Draft_Pick_Number NUMBER, Draft_Class CLOB, College CLOB)
CREATE TABLE team (Team_id NUMBER, Name CLOB)

Show me a bar chart for how many players are from each country?
SELECT Country_name, COUNT(*) FROM country AS T1 JOIN match_season AS T2 ON T1.Country_id = T2.Country GROUP BY T1.Country_name
SELECT "Country_name", COUNT(*) FROM "country" "T1" JOIN "match_season" "T2" ON "T1"."Country_id" = "T2"."Country" GROUP BY "T1"."Country_name"
