<p>A simple <code>google-chart</code> looks like this:</p>
<google-chart
cols='[{"label": "Data", "type": "string"},{"label": "Value", "type": "number"}]'
rows='[["Something", 1]]'>
</google-chart>
<p>Charts can be resized with CSS, but you'll need to call the <code>drawChart</code> method when the size changes.</p>
<p>Here's a basic responsive example using only CSS and JS. You could also use <code><iron-media-query></code>.</p>
<style>
/* Phone and tablet */
#resizing_chart {
height: 300px;
width: 400px;
}
/* Desktop */
@media screen and (min-width: 1024px) {
#resizing_chart {
width: 800px;
}
}
</style>
<script>
var media = window.matchMedia('(min-width: 1024px)');
media.addListener(function() {
document.getElementById('resizing_chart').drawChart();
});

<p>Here's a pie chart with an area selection:</p>

<p>Here's a chart defined using <code>data</code>, rather than <code>rows</code> and <code>cols</code>:</p>

["2007", 1030, 540]]'>

<p>And one with some pretty complicated styling, where the data is loaded from an external JSON resource using the <code>data</code> attribute:</p>
<google-chart
type='column'
options='{"title": "Bar height", "legend": "none"}'
data='chart-data.json'>

<p>Website traffic data by country from an external JSON resource where the data is in raw DataTable format.</p>
