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 screen_mode ( Graphics_mode real, Char_cells text, Pixels text, Hardware_colours real, used_kb real, map text, Type text )
TABLE: CREATE TABLE chip_model ( Model_name text, Launch_year real, RAM_MiB real, ROM_MiB real, Slots text, WiFi text, Bluetooth text )
TABLE: CREATE TABLE phone ( Company_name text, Hardware_Model_name text, Accreditation_type text, Accreditation_level text, Date text, chip_model text, screen_mode text )

### Question ###
Compare the number of chips from different company names for the phone whose screen mode type is 'Graphics' with a bar chart, could you order by the X from high to low?

### Accurate SQL ###

SELECT Company_name, COUNT(Company_name) FROM screen_mode AS T1 JOIN phone AS T2 ON T1.Graphics_mode = T2.screen_mode WHERE T1.Type = "Graphics" GROUP BY Company_name ORDER BY Company_name DESC
