A black and gray SVG Line chart

View the bare-bones, stripped-down version of this demo

A straightforward Line chart that's showing UFO sightings over the past century. As you can see - people's creativity is clearly on the increase - particularly since the 1990s!

The background grid is customised with white and an increased number of vertical lines.

The X-axis labels are just years, the axes have been turned off and the tickmarks for the line are filled circles.

On the whole, it's a pretty regular Line chart. The responsive configuration just shrinks the size of the chart and reduces the size of the linewidth and the tickmarksSize options.

This goes in the documents header:
<script src="../libraries/RGraph.svg.common.core.js" ></script>
<script src="../libraries/RGraph.svg.line.js" ></script>
Put this where you want the chart to show up:
<div style="float: right">
    <div style="width: 600px; height: 250px" id="chart-container"></div>
This is the code that generates the chart - it should be placed AFTER the <div> tag:
