I'm having a really weird issue while trying to visualize this scatter plot
using the google visualization API.
Basically, if I put the first data point as [0,0] everything will be fine,
but if remove [0,0] as the first point, the chart won't produce. I checked
the console and this is what I said:
"Uncaught SyntaxError: Unexpected token <
Uncaught Error: Invalid value in 0,0"
Why exactly does the first point need to be [0,0]?

<head>
<script type="text/javascript" src="https://www.google.com/jsapi";></script>
<script type="text/javascript">
google.load("visualization", "1", {packages:["corechart"]});
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Camera','Avg Rating'],
[ {v:6000, f: 'Canon EOS-1Ds Mark III'}, 60],
[ {v:5000, f: 'Canon EOS-1Ds Mark II'}, 50],
[ {v:4000, f: 'Canon EOS-1D Mark IV'}, 40]
]);
var options = {
title: 'Breakdown of Camera Models by Price, Photo Rating and Brand',
hAxis: {title: 'Price (USD)', minValue: 0, maxValue: 7500},
vAxis: {title: 'Avg Rating (at peak)', minValue: 0, maxValue: 55},
legend: 'none'
};
var chart = new
google.visualization.ScatterChart(document.getElementById('chart_div'));
chart.draw(data, options);
}
</script>
