Test project files:
1) step1.html : demonstration only using javascript. data may be embedded directly into javascript source code. Note that the data isn't actually hard coded into the HTML page. Contents of a text file (polygons.txt) is accepted as an input in a text area. The points that will compose the polylines will then be parsed from the file.

2) step2.php : demonstration of PHP code, which loads map data from a file, and dynamically creates the polylines within PHP code (Map data is set in PHP code - and displayed using Javascript). Somehow works like step1, but the text file (polygons.txt), is automatically loaded and parsed.

3) step3.html : combined step3 and step4.
- step 3 : demonstration of using a thick blue line for any county border which is a state border - use a thin red line for any county border which is a border with another Delaware county. Contents of a text file (boundary.txt) is accepted as an input in a text area.
- step 4 : overlay an image of the county name in the center of each county. Image files (newcastle.jpg, kent.jpg, sussex.jpg) are found in the same directory.
