Project: svg-chart
Task (moderate): In `common/Chart.js`, when `options.axes` is true or not defined:
- append axis-x labels (class `label label-{index}`, color black) inside `.axes-x` and align them to the bottom
  - axis-x labels, coming from `data.labels`, are evenly distributed from left to right, `.label-0` is aligned to the left of `.axes-x`
- append axis-y labels (class `label label-{index}`, color black) inside `.axes-y` and align them to the left
  - The min and max axis-y values correspond to the min and max values of `dataset.data`
  - 6 axis-y labels, ranging from the min to the max, are evenly distributed across 5 sections from bottom to top, `.label-0` is aligned to the bottom of `.axes-y`
