InnerHTML Placement

I have recently decided to re-approach a function in the code I have been working on based on the recommendations of a few of you helpful folks. The current function takes data accumulated from form calculatiions, formats it for display then opens a fresh window and writes that data into the document using the document.write() method. This presented me with a bit of a problem when it came to saving the document, particularly in Internet Explorer. When I brought that problem up here on the boards, it was suggested that I go from document.write() to innerHTML and rather than open a blank document, I should open a document that at least has the basic coding set up, such as DOCTYPE, HEAD and BODY tags.

This is all fine and dandy and I understand the basic concepts of how it is supposed to work, but in working through the logic of the process, I discovered that my weakness in understanding how to implement the innerHTML method is holding me back a bit. So now I come seeking advice once more, however, before I go any further with this, let me explain how the document is meant to be displayed.

The data is sent to the document in two basic stages. The first of those stages is a visual or "graphical" representation of the data and consists of a foundation image (in this case, a polar chart) with secondary images (stellar bodies and/or stars) placed on top of it to represent the data in a positional format (basicly stars positioned by Right Accension and Declination Angle).

The second stage of the data transfer (which, at this point, I don't see any problem coding since it is pretty straight forward) is a text rendering of the processed information in a tabular format. For the most part, I intend to keep it in tabular format and simply send it to a specific DIV element.

My difficulties are coming from the first stage of the process. My first thought was to load the foundation image from the popup itself rather than using the function to insert it in the document and then send the positioning data to the document as a series of DIV elements in much the same fashion as I was doing before. These DIV elements, or so I assume, when sent to the document, would have to be placed in the body of the document in general. Therefore, I would assume that the body would have to have a name/id attribute that innerHTML could access. My question here is, where exactly does that data go when it is sent. Assuming the basic document has the following appearance; Code:
