Updated SVG Demos
Further to this morning's post about SVG I've been back and looked for this site's old SVG demos. What I found was that all (well, both) of my SVG demos were broke, as the current browser implementation of SVG requires a content-type of "image/svg+xml" and I wasn't specifying that. Doh.
The main demo I fixed was the World Cup goals summary database. The SVG chart from it is embedded below.
Whether you see the chart below depends on what browser you're using. If you're using IE you won't see it. If you're using any other up-to-date browser you should see a bar chart of the goals scored in the first round of the cup, by group.
I remember being much more proud of that when I did it than I am now looking at it again. How times change.
Note that the chart you're seeing above is not just an image (as such) and is not Flash and is built in real-time based on backend data in Domino. Scale your browser window and notice is scaled with it (vector-based!). Right click the chart and you can even view its SVG source, just like HTML!
While there are various charting solutions available now, most rely on Flash, while SVG is much more "pure". When HTML 5 is out and about there'll even be and <svg> tag, so you can add a chart inline with your HTML like so:
<html>
<body>
<h1>SVG/HTML 5 Example</h1>
<svg>
<circle id="myCircle"
cx="100" cy="75" r="50"
fill="blue"
stroke="firebrick"
stroke-width="3" />
<text x="60" y="155">Hello World</text>
</svg>
</body>
</html>
Stay ahead of the game and familiarise yourself with SVG now. At some point in the future it will be a really useful tool. If it isn't already.
For more Domino-based SVG inspiration, it's good to see that Ruediger Seiffert's Agent-generated pie chart is still online.
For now I think I'll forget about SVG, as I have other things on my mind, but it's good to see it progressing and that whatever I haven't forgotten from my first foray in to SVG isn't going to have been learnt in vain.

Jake,
I'm using IE 6 (don't ask), and I can see the chart.....
Phil.
I assume you must have the Adobe (or some other) SVG viewer plugin installed then Phil?
As usual Jake, you were so far ahead of the curve that you are driving around the track and closing in on... yourself!
Excellent work
Well, if you say so Ed ;o)
Thinking about it I wonder if it's still too early to take SVG seriously. After all, without native support in IE how can we consider it for real-world use?!
Jake - Just checked, and yes I do have the Adobe plug-in installed.
Good stuff as usual, Phil.
Thanks for mentioning my really ancient example. To be honest it's a little bit rusty and somehow broken... Today i am more excited by Flex (with or without Domino).
Although SVG is great for generating dynamic images/ charts, most of our users are using IE. We therefore has to resort to generating PNG images from SVG content server side using the Apache Batik library (http://xmlgraphics.apache.org/batik/).
The SVG XML is generated in an agent and (using LS2J) sent to a Java class that creates the PNG file. The generated images are attached to a Notes document and referenced in a report. See the Batik Transcoder API for an example.
Cheers,
Mark
