CREATE TABLE match_season (Season FLOAT, Player TEXT, Position TEXT, Country INT, Team INT, Draft_Pick_Number INT, Draft_Class TEXT, College TEXT)
CREATE TABLE team (Team_id INT, Name TEXT)
CREATE TABLE country (Country_id INT, Country_name TEXT, Capital TEXT, Official_native_language TEXT)
CREATE TABLE player (Player_ID INT, Player TEXT, Years_Played TEXT, Total_WL TEXT, Singles_WL TEXT, Doubles_WL TEXT, Team INT)

Show me a bar chart for how many players are from each country?, could you list in desc by the X-axis?
SELECT Country_name, COUNT(*) FROM country AS T1 JOIN match_season AS T2 ON T1.Country_id = T2.Country GROUP BY T1.Country_name ORDER BY Country_name DESC
SELECT "Country_name", COUNT(*) FROM "country" AS "T1" JOIN "match_season" AS "T2" ON "T1"."Country_id" = "T2"."Country" GROUP BY "T1"."Country_name" ORDER BY "Country_name" DESC NULLS LAST
