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 submission ( Submission_ID int, Scores real, Author text, College text )
TABLE: CREATE TABLE workshop ( Workshop_ID int, Date text, Venue text, Name text )
TABLE: CREATE TABLE Acceptance ( Submission_ID int, Workshop_ID int, Result text )

### Question ###
Show each author and the number of workshops they submitted to with a bar chart, and display by the x-axis from low to high.

### Accurate SQL ###

SELECT Author, COUNT(DISTINCT T1.Workshop_ID) FROM Acceptance AS T1 JOIN submission AS T2 ON T1.Submission_ID = T2.Submission_ID ORDER BY Author
