Recommended Web Browser: All of the major browsers are now supporting SVG and we have upgraded all our maps to a common format which will work better. We have tested 5 major browsers on a variety of systems. The following table lists our results. Your results may be slightly different depending on how options are set. Most of our testing has been done on Windows PCs, results on Mac computers may vary. Look at the samples to see how the maps will work on your system.

If someone knows of a zoom extension for Chrome please let me know.
Popup Information: Information about the country that will appear in a popup window as the mouse hovers over a name. There may be a slight delay in appearing.
General Information:
These maps are designed to work as follows. For the maps on the CD, once you insert the CD the file index.htm should open in your default web browser.
This will display the master index with years and clicking on any one of them will bring up the svg file for that year.
If you copy all the files on to your hard drive the same procedure should work if you start from the index.htm file.
If the index does not open automatically you will then need to open the index.htm file in your browser.
You can do this by using the file menu, or by dragging the file into an open browser window, or by right clicking on the index file and selecting open with.
You can open any of the svg files directly by the same means.
For each year there is an svg file. The only reason that you would not be able to open the svg file directly would be that you have some other program defined as the default program to open svg files.
SVG is a standard of the World Wide Web Consortium but each browser has defined its implementation differently.
Note: These maps require significant system resources and may not work properly on older computers. Performance will also be slower when viewing the samples on the web. For fastest performance we suggest copying the contents of the CD to your hard drive. The maps display in layers and a slight delay may be experienced while layers are being drawn.
