Please clarify your requirements. Is it:
1. Read a file that has no fixed size in chunks of 100 characters.
2. Count the occurance of A,G,C,T in the above 100 characters.
3. Draw a bargraph for the above - 1 bargraph in a line for each 100 chars.
4. Stop when count of A,G,C,T reaches 100.
Please state your specs in simple statements like above.
