<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" 
        integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" 
        crossorigin="anonymous">
</script>
<script src="jquery.subwayMap-0.5.0.js"></script>

2. Create a container for the legend to help readers understand the map data.

<div id="legend"></div>

3. Add your own nodes and routes to the Subway Map using following data attributes:

• data-columns: The number of columns.
• data-rows: The number of rows.
• data-cellSize: The width and height of each cell in pixels.
• data-legendId: The ID of the map legend.
• data-textClass: The CSS class to use for text labels.
• data-grid: show or hide a grid that is useful during map construction.
• data-gridNumbers: True or false, to show or hide numbers on the grid.
• data-lineWidth: The width in pixels for each line. 
• data-color: The color of the line.
• data-label: The label for the line that will be displayed in the legend.
• data-outline: doubles each line with a white one to get an outline effect
• data-coords: The X,Y coordinate pair where the line should be drawn to from its last location .
