It looks like Chart API is the most attractive idea for GSoC+POI, three students already expressed interest in it.
I think good starting points to write a proposal would be: 1. familiarize yourself with charts in Excel in general: you need to understand the product you are going to write a API for. See what types of charts are supported in Excel and how you can construct them, how to set legends, titles, etc. 2. Start learning the POI code. Focus on the HSSF and XSSF modules. Support for charts will be based on common Spreadsheet interfaces and there will be two implementations: one for HSSF (.xls format) and the other for XSSF (.xlsx format). 3. Download the format spec from Microsoft, follow instructions at http://poi.apache.org/guidelines.html. You will need the spec for both binary (.xls) and OOXML (.xlsx) formats. In your proposal you will need to sketch a Implementation plan and a Timeline and to write them you need basic understanding of the project structure.
