You have a duplicate google.load call, so delete this:
<script type="text/javascript">
google.load('visualization', '1', {packages: ['gauge']});
</script>
I don't think that is the cause of your problem though. If it doesn't fix
the problem, comment out this line and see what happens:
json = JSON.parse(json);
