Show all the activity names and the number of faculty involved in each activity in a bar chart, could you sort activity_name in descending order?
SELECT activity_name, COUNT(*) FROM Activity AS T1 JOIN Faculty_Participates_in AS T2 ON T1.actid = T2.actid GROUP BY T1.actid ORDER BY activity_name DESC
SELECT "activity_name", COUNT(*) FROM "Activity" "T1" JOIN "Faculty_Participates_in" "T2" ON "T1"."actid" = "T2"."actid" GROUP BY "T1"."actid" ORDER BY "activity_name" DESC
