| <h2>A line chart</h2> | |
| <p>The following bar chart was created using d3.js. The data shows the amount of energy produced from five sources - coal, oil, uranium, gas and renewable sources - in Australia, from 1977 to 2013, in Petajoules (10<sup>15</sup> Joules). Each line represents an energy source.</p> | |
| <p>Hover over the labels at the right to highlight the respective line. Hover over the lines to see more details.</p> | |
| <div id="svganchor"></div> | |
| <br> | |
| <p>Line charts are good for comparing values among different groups, in this case among different energy sources, in a time series.</p> | |
