Improvements[edit]
1. The illustration image is bad. It's from the Douglas-Pecker algorithm.
2. Advantages: For geographical maps, V-W usually generates better visual results than D-P.
3. Disadvantages: The basic Visvalingam–Whyatt algorithm may generate self intersections, not allowed in many applications. The modified V-W-algorithm takes care of this problem.
4. It may worth to link https://www.jasondavies.com/simplify/ It's a working JavaScript implementation of the modified V-W with explanation.
