Accessing sqlite database and showing graph on browser

I am working on an academic project which aims the following:

1. I have a sqlite database which contains data in a tabular format

2. I want to access the sqlite database and draw graph based on the values of two columns.

3. This graph I have to show on a browser.

For this I am taking following approach:

1. I have written a java program (shown below) which accesses the sqlite database and shows the graph.
2. Now my next step is to connect my java program with javascript and show the graph on a browser.

First of all I would like to know whether my approach is correct and if yes, please suggest the way how to move ahead.I am not versed with programming languages so please help me with your esteemed support.
