ropeChart
The rope chart provides a simplified visualization of where a particular value lies within a group.
Getting Started
For now, you must use a script tag to include ropeChart. D3 must be available in the global namespace as well. Download ropeChart.js, put something like the following in your and you should be good to go.
<script src="d3.js" charset="utf-8"></script>
<script src="ropeChart.js" charset="utf-8"></script>Example
HTML would look something like this
<!DOCTYPE html>
<html lang="en-US">
<head>
<script src="d3.js" charset="utf-8"></script>
<script src="ropeChart.js" charset="utf-8"></script>
</head>
<body>
<div id="myRopeChart"></div>
</body>
<script src="index.js"></script>
</html>And the index.js here would contain something like this
var data = {
min: {value: 5, label: 'Country A'},
max: {value: 95, label: 'Country B'},
threshold: {value: 60, label: 'Region Average'},
focus: {value: 45, label: 'Mongolia'}
}
var myRopeChart = ropeChart('div#myRopeChart');
.data(data)
.width(250)
.height(250)
.ropeWidth(10)
.knotRadius(10)
.render();API Reference

new ropeChart(selection)
Rope chart implementation.
Returns: ropeChart - s
