An SVG Bar chart showing the inflation rate over the past year

This goes in the documents header:
<script src="RGraph.svg.common.core.js"></script>
<script src=""></script>
Put this where you want the chart to show up:
<div style="width: 750px; height: 300px" id="chart-container"></div>
This is the code that generates the chart:
    data = [3.1,3,3,2.7,2.5,2.4,2.4,2.4,2.5,2.7,2.4,2.4];        
    max = 3.5;

    bar = new RGraph.SVG.Bar({
        id: 'chart-container',
        data: data,
        options: {
            xaxisLabels: ['','','Jan 2018','','','Apr 2018','','','Jul 2018','','','Oct 2018'],
            xaxisTextBold: true,
            xaxis: false,
            yaxisScaleMax: 3.5,
            yaxisScaleDecimals: 1,
            yaxisScaleUnitsPost: '%',
            yaxis: false,
            labelsAbove: true,
            labelsAboveDecimals: 1,
            labelsAboveUnitsPost: '%',
            title: 'UK Inflation over the past 12 months',
            textSize: 9,
            hmargin: 10,
            colors: ['Gradient(#4682B4:#76B2E4)'],
            backgroundGridDotted: true,
            shadow: true
