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

Show me about the distribution of Date_of_Birth and Weight in a bar chart, and could you rank by the y axis from low to high?
SELECT Date_of_Birth, Weight FROM people ORDER BY Weight
SELECT "Date_of_Birth", "Weight" FROM "people" ORDER BY "Weight" NULLS FIRST
