Mere ignorance on his part - and on the part of respondents who have not
noticed that.

Draft standard HTML 5, and current versions of Firefox, Opera, Safari,
and Chrome have the <canvas> element.

One can draw diagrams on it with JavaScript code (in a PostScript-like
manner), one can get the result as a PNG string, one can load the PNG in
an IMG, and (manually) "Save As" that to disc.

Publish the code, and others can modify the figure; publish the saved
figure, and they can just admire it.

For a demo, see <$lag-pts.htm>; set
"Together" and some checkboxes, and press "Run".

Then see <>. For actual use,
take (but do not republish) a copy of the page and its include file.
Full usage direct from Web should not be permanently supported.

However, what browsers really need is

<script type="Text/pascal"> and <script type="Text/delphi">.
