Though graphical, this demo doesn't use binary image files such as GIF, JPEG, and PNG, but consists only of text data.

This version doesn't even require the capability to render SVG but is less fine. An XHTML+SVG version is recommended if your browser can render SVG.


Provided that your computer doesn't have a trouble, all of the background colors in 3 by 3 cells are pure white.

Just the inner edges of cells are colored.

If you see colored backgrounds of cells, your "seeing" is nice.

The inside colors of small squares within each cell are also pure white.

If you see different background colors of a cell and of a square within it, your "seeing" is very nice.
