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 Services ( Service_ID INTEGER, Service_name VARCHAR(40) )
TABLE: CREATE TABLE First_Notification_of_Loss ( FNOL_ID INTEGER, Customer_ID INTEGER, Policy_ID INTEGER, Service_ID INTEGER )
TABLE: CREATE TABLE Settlements ( Settlement_ID INTEGER, Claim_ID INTEGER, Effective_Date DATE, Settlement_Amount REAL )
TABLE: CREATE TABLE Customers ( Customer_ID INTEGER, Customer_name VARCHAR(40) )
TABLE: CREATE TABLE Customers_Policies ( Customer_ID INTEGER, Policy_ID INTEGER, Date_Opened DATE, Date_Closed DATE )
TABLE: CREATE TABLE Claims ( Claim_ID INTEGER, FNOL_ID INTEGER, Effective_Date DATE )
TABLE: CREATE TABLE Available_Policies ( Policy_ID INTEGER, policy_type_code CHAR(15), Customer_Phone VARCHAR(255) )

### Question ###
Give me a histogram to show the ordered list of customer ids?

### Accurate SQL ###

SELECT Customer_name, Customer_ID FROM Customers ORDER BY Customer_ID
