This is a library to generate SVG sparklines like this
Here was the rainfall for the year 2012 in the UK
Use the library like this:
<script src="sparklines.js"></script> <span class="sparkline" data-values="1,4,3,6,5"></span> <span class="sparkline sparkline-filled" data-values="1,4,3,6,5"></span>
Anything with the sparkline class will get an SVG sparkline made from the values in data-values appended. Add the class sparkline‑filled for a filled sparkline like above.
It's not a bad idea to add style too:
.sparkline svg {
stroke: mediumseagreen;
stroke-width: 1.5px;
}
.sparkline-filled svg {
fill: rgba(60,179,113,0.25);
}
