> Right now we rely on "eval" to decode json results in the monitor display:
> [vis.js|https://github.com/apache/accumulo/blob/master/server/monitor/src/main/resources/web/vis.js#L85]
> {code}
> function handleNewData() {
>   if (xmlhttp.readyState!=4) {
>     return;
>   }
>   if (xmlhttp.status!=200 || xmlhttp.responseText==null) {
>     xmlReturned = true;
>     return;
>   }
>   var newstats = eval('(' + xmlhttp.responseText + ')');
> {code}
> We should instead use JSON.parse
