WordPress shortcode to embed Google trends graphs

The first step is to create the shortcode. To do so, open your functions.php file and paste the code below in it:

function wps_trend($atts){
        extract( shortcode_atts( array(
                'w' => '500',           // width
                'h' => '330',           // height
                'q' => '',              // query
                'geo' => 'US',          // geolocation
        ), $atts ) );
        //format input
        $h=(int)$h;
        $w=(int)$w;
        $q=esc_attr($q);
        $geo=esc_attr($geo);
         ob_start();
?>
<script type="text/javascript" src="http://www.google.com/trends/embed.js?hl=en-US&q=<?php echo $q;?>&geo=<?php echo $geo;?>&cmpt=q&content=1&cid=TIMESERIES_GRAPH_0&export=5&w=<?php echo $w;?>&h=<?php echo $h;?>"></script>
<?php
return ob_get_clean();
}
add_shortcode("trends","wps_trend");

Once you saved your functions.php file, you can now use the shortocode in your posts and pages. Here is an example of usage:

[trends h="450" w="500" q="wpsnipp,wordpress,+wordpress+theme,+wordpress+plugin,+wordpress+snippets" geo="US"]

Thanks to Kevin Chard for the shortcode!
