CREATE TABLE candidate (Candidate_ID NUMBER, People_ID NUMBER, Poll_Source CLOB, Date CLOB, Support_rate FLOAT, Consider_rate FLOAT, Oppose_rate FLOAT, Unsure_rate FLOAT)
CREATE TABLE people (People_ID NUMBER, Sex CLOB, Name CLOB, Date_of_Birth CLOB, Height FLOAT, Weight FLOAT)

Give me the comparison about Weight over the Date_of_Birth by a bar chart, order in descending by the y-axis.
SELECT Date_of_Birth, Weight FROM people ORDER BY Weight DESC
SELECT "Date_of_Birth", "Weight" FROM "people" ORDER BY "Weight" DESC
