All the states in India are listed along the x-axis. The stack of accidents in each of the four years is shown along the y-axis. The color of each bar differentiates the contribution of accidents each year. Source: <a href="https://data.gov.in/keywords/indian-road-accident-data">data.gov.in</a>, 2015 </p> <label><input type="checkbox"> Sort values</label> <svg id="mySvg"></svg> <p>A check box is provided to arrange the states by the number of accidents. Unchecking the box re-arranges the states alphabetically. There are few issues that still need to be resolved. For example, getting the state names initially is not very intuitive.
