Polymer 1.0 Is there any ready made chart element? - pie-chart

Question

I want to add a pie chart in my Polymer 1.0 application. I used chart-elements with Polymer 0.5, but when migrated to 1.0 it stopped working!
I did not find anything for 1.0 yet. Does 1.0 at all has a ready made chart element? Seeking for expert help.
Thanks in advance.
EDIT
According to Ben's suggestion I tried with google-chart component and this is what I did. But the chart is not rendering.
Step 1: I installed google-chart by using bower install --save GoogleWebComponents/google-chart
Step 2: Created a custom element using yo polymer:el custom-pie-chart which looks like this:
<dom-module id="custom-pie-chart">
<style>
:host
{
display: -webkit-flex;
display: -ms-flex;
display: flex;
margin: 0;
padding: 0;
width: 400px;
height: 300px;
}
#chartdiv
{
width: 100%;
}
google-chart
{
height: 300px;
width: 50em;
}
</style>
<template>
<link rel="stylesheet" href="custom-pie-chart.css">
<div id="chartdiv">
<google-chart
type='pie'
options='{"title": "Distribution of days in 2001Q1"}'
cols='[{"label":"Month", "type":"string"}, {"label":"Days", "type":"number"}]'
rows='[["Jan", 31],["Feb", 28],["Mar", 31]]'>
</google-chart>
</div>
</template>
</dom-module>
<script>
(function () {
Polymer({
is: 'custom-pie-chart',
ready: function () {
}
});
})();
</script>
Step 3: Added references of google-chart and my custom element custom-pie-chart in elements.html
Step 4: Added custom-pie-chart in my index.html as follows:
<post-card id="sales-info" title="Points from customer">
<custom-pie-chart></custom-pie-chart>
</post-card>
But chart is not rendering. Area comes blank like this:
NB: I am also getting the following error on console (Chrome)
Uncaught (in promise) TypeError: Request method 'POST' is unsupported
at TypeError (native)
at http://localhost:3000/bower_components/sw-toolbox/sw-toolbox.js:20:430
I removed all references of google-chart to check whether this is responsible. But it still comes up.
What wrong I am doing? Please help!

Answer 1

This causes the error:
rows='[["Jan", 31],["Feb", 28],["Mar", 31]]'
because Polymer only recognizes rows='[[...]]' and thinks it is a data binding. Two spaces should solve the problem:
rows='[ ["Jan", 31],["Feb", 28],["Mar", 31] ]'
