Am looking to use this module and was wondering if it is possible to style the output. I have seen something similar with the polls module which use the charts api and was wondering how I would go about creating something similar to do something similar with decisiions?

OK carrying on from before, put this in your template.php file (don't forget to change mytheme to your theme name)

function mytheme_preprocess_poll_results(&$variables) {
  //theme the poll results block

  $html = $variables['results'];
  $pattern = "@class=\"text\"\>(.*)\</div\>@";
  preg_match_all($pattern, $html, $choices); //extract choices
  $pattern = "@style=\"width: (.*)%;\"@";
  preg_match_all($pattern, $html, $votes); //extract percentages

  $chart = array(
    '#chart_id' => 'poll_chart',
    '#type' => CHART_TYPE_PIE_3D,
  );
// NEED TO FILL IN DATA TO MAKE CHART
  for ($c=0; $c < count($choices[1]); $c++) { //make labels and values
     $chart['#data'][$choices[1][$c]] = $votes[1][$c]; //number of votes
     $chart['#legends'][] = $choices[1][$c] . " (" . $votes[1][$c] . "%)"; // labels
  }
  $variables['results'] = chart_render($chart); //render graph
}
copy the poll-results-block.tpl.php to your template folder and make it something like

<div class="poll">
  <h3 class="title"><?php print $title ?></h3>
  <?php print $results ?>
</div>
And now your results block should contain the graph.
