CREATE TABLE railway (Railway_ID NUMBER, Railway CLOB, Builder CLOB, Built CLOB, Wheels CLOB, Location CLOB, ObjectNumber CLOB)
CREATE TABLE manager (Manager_ID NUMBER, Name CLOB, Country CLOB, Working_year_starts CLOB, Age NUMBER, Level NUMBER)

Create a bar chart showing the total number across builder, and could you rank Y in desc order?
SELECT Builder, COUNT(*) FROM railway GROUP BY Builder ORDER BY COUNT(*) DESC
SELECT "Builder", COUNT(*) FROM "railway" GROUP BY "Builder" ORDER BY COUNT(*) DESC
