Error showing data with Spark Highcharts

I'm having error trying to show graphical view of a csv data with spark-highcharts.

As you can see, the last sentence works well, it looks like the process y working because it takes more than one minute to finish, but the browser console, shows the following and the graphic is missing:

The paragraph also reservate space for showing results, but is a white space.
