This a very old thread, but it still turns up in searches. Here's a simple way to do a crude version of what the original poster was doing. That is, a display of the most recent wind direction on the background of a compass rose, not a wind rose, showing history. May not work in all browsers, but hasn't failed me yet.
Add the following code to index.html.tmpl. I created a table with one row of two cells at the top of the page, put the masthead text in the left cell and this in the right cell: <svg version="1.1" baseProfile="full" width="200" height="200" xmlns="http://www.w3.org/2000/svg";> <circle cx="90" cy="85" r="75" stroke="black" stroke-width="5" stroke-dasharray="1,12.08" fill="transparent" /> <circle cx="90" cy="85" r="80" stroke="lightgray" stroke-width="10" fill="transparent" /> <polygon points="90 35, 100 75, 140 85, 100 95, 90 135, 80 95, 40 85, 80 75" fill="lightsalmon" transform="rotate(45 90 85)" /> <polygon points="90 25, 100 75, 150 85, 100 95, 90 145, 80 95, 30 85, 80 75" fill="salmon" /> <text x="90" y="22" font-size="16" text-anchor="middle" fill="gray">N</text> <text x="90" y="159" font-size="16" text-anchor="middle" fill="gray">S</text> <text x="22" y="91" font-size="16" text-anchor="middle" fill="gray">W</text> <text x="158" y="91" font-size="16" text-anchor="middle" fill="gray">E</text> <circle cx="90" cy="85" r="20" stroke="black" fill="white" /> <text x="90" y="90" font-size="16" text-anchor="middle" fill="black">$current.windSpeed.formatted</text> #if $current.windDir.formatted != " N/A" <polygon points="90 20, 95 65, 85 65" fill="black" transform="rotate($current.windDir.formatted 90 85)" /> #end if </svg> I hope someone finds this helpful, and that someone will improve on it.
