Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE market ( Market_ID int, District text, Num_of_employees int, Num_of_shops real, Ranking int )
TABLE: CREATE TABLE phone ( Name text, Phone_ID int, Memory_in_G int, Carrier text, Price real )
TABLE: CREATE TABLE phone_market ( Market_ID int, Phone_ID text, Num_of_stock int )

### Question ###
Give me a bar chart to visualize the number of the districts of markets they are on, and list by the total number from high to low.

### Accurate SQL ###

SELECT District, COUNT(District) FROM phone_market AS T1 JOIN market AS T2 ON T1.Market_ID = T2.Market_ID JOIN phone AS T3 ON T1.Phone_ID = T3.Phone_ID GROUP BY District ORDER BY COUNT(District) DESC
