 JavaScript  で描画を行うライブラリ。
http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm

ソースは 5KB と軽量なのに、 JavaScript  を使ってウェブページ上に
任意の直線・長方形・ポリゴン・円(だ円)が描ける。
さらにペジェ曲線とかも描けたら面白いかも?

サンプルの通りにスクリプトを書いてみたが、ページ全体には描けたけど
<DIV></DIV> 範囲をキャンバスとした場合は表示されなかった。 バグかなぁ?

---
内部的には、1ピクセルずつ <DIV></DIV> を生成しているらしい。
つまり、線や円を描いただけで、大量のタグを使って図形が表示される。
処理速度パフォーマンスは△だけど、簡単な図形なら、意外なほど問題ない速度。
