Ron, I recall we once discussed this in a different topic, but I cannot find this here. I have a very large tree, where the SVG scrolls VERY slowly. Is there another solution to show this tree graphically, which will speed up the scrolling? Is there something that can be done with the SVG itself? If so, is there a simple algorithm that you can provide Dan to determine which method should be used as a default? For example, if there are more than 500 elements, use a lower quality ...

I think splitting a large family into smaller sub-trees (GenoMaps) will speed-up the drawing which will improve the scrolling.

I hate to admit it but IE6 with Adobe plugin is more responsive than FireFox for such things as scrolling

People (myself included) like to see the whole tree and where they are in relation to others. I guess I am looking for a better solution.

Hi Danny.I have the same problem, and with large trees the SVG scrolls so slowly, that I can't use it at all. My solution was to export the graphic tree to EMF and then to convert it to PNG. Users can scroll the PNG Tree very fast without any problem. I know it's not a sophisticated solution, but it's better for me then nothing.

Yes if you want the whole large tree in one genogram then speed becomes an issue. Adobe SVG Viewer is faster than FireFox especially when you use the built-in panning and zooming controls instead of clicking the green panning arrows and zoom icons.
Perhaps a Flash graphic may be a solution, one which I have briefly looked at producing, particularly using the Flash scripting solution SSWF, but it is on the back burner at present, so could be a long way off, perhaps never! (unless there are some Flash programming gurus out there who could give it a shot).
There is always the option of using the GenoPro ActiveX control and viewing the tree that way (just uncheck the 'No .gno file' in the Privacy tab). But it doesn't work with Firefox 
But the only reason I see for a single genogram is the ability to print it as a single document. Do you have other reasons other than wanting to see where you sit?
I use an overview genogram giving a block view showing the linkage of the other genograms. I use dummy hyperlinks to move from and back to the overview, and link the hyperlinks on the overview with 'social relationship' arrows.

I have learned over the years that there are a number of methods by which people view information. One is usng the written word, while another is visual. For those who see a picture and can recognize a thousand words, the best method of viewing a tree is in a graphical format where the entire tree is available in one view.It is a matter of taste, but I do believe it worthwhile to see a tree as a whole. If it can be seen technically, there is no reason it cannot be viewed and scrolled within a reasonable timeframe.
