Dimple.js simple time chart

Dimple.js - Simple data visualization chart

This is an example of a corrected chart from the 'Tokyo' Wikipedia article which contains a chart without proper x-axis labels and spacing.

Critique

The x-axis ticks from year 2005 represent just one year, which is misleading for the reader.
The messages overlapping the chart are not necessary now that the horizontal grid lines show when the specific population number is exceed.

_{NOTE: This example is a mini-project for the Udacity's Data Visualization and D3.js course.}
