[Editor's Note: If your browser does not support SVG images, you should be seeing PNG images instead, which will not look as good as the SVG versions. If you don't see any images, let me know what browser, version, etc. you are using. It seems some of the popular browsers out there don't "do the right thing" hmph!]

I’ve been working on some simple graphing utilities in Perl to create SVG graphs… Here’s a few samples…
Our cost for phone service seems to have gone down.
Local utilities continue to rise. Ugh…
We’re spending less on food, well, most of the time. ;)
I like the fact that these are very simple, showing just the trend and not going into details like month, amount, etc. In fact, to create one of these just takes the following:
perl ggraph2.pl "Phone" "44 54 50 53 44 41 43 53 42 42 44" >phone.svg
Run the script passing in the name you want on it, and a string of numbers space separated, and output it to a file. It’s still a bit fragile, and only does some basic normalizing, so wacky things will break it, but it’s a start. Like all other quick little hacks, in the hands of the guy who wrote it, it “gets the job done” while users would break it in less than 10 minutes and start yelling.
I really like SVG. It reminds me of the old days of plotting out graphics on the Apple ][+ and that’s a good thing! It’s another one of those “edge technologies” I keep hoping will finally catch on big one of these years…
