What is the sum of credit value of courses with more than one prerequisite for each title? Return a bar chart, rank in asc by the x-axis.
SELECT title, SUM(credits) FROM course AS T1 JOIN prereq AS T2 ON T1.course_id = T2.course_id GROUP BY title ORDER BY title
SELECT "title", SUM("credits") FROM "course" "T1" JOIN "prereq" "T2" ON "T1"."course_id" = "T2"."course_id" GROUP BY "title" ORDER BY "title"
