- To change the metric represented by the size of the bubble use the 'size' combo box to the right of the chart.
- Click on the pull down box of an axis' label to change the metric that is displayed on an axis or in a table. Other PingER metrics that are available include minimum RTT, jitter and unreachability.
- Move the mouse over a bubble to identify the values for the bubble.
- Linear or logarithmic scales may be selected using the combo box along the axis.
- Move the mouse over a coloured legend symbol to blink the balloons associated with the symbol's color.
- To follow the changes in detail simply move the slider bar with the mouse.
- One can select a bubble by clicking on it to provide a label for the bubble that persists with the motion. The trails check box leaves a trail to follow the motion of selected bubbles. N.B. selected bubbles determine how far the data to be displayed goes back in time.
- By clicking the links at the right top of the page, one may select the vantage point, the observed region and the granularity of the measurements.

Miscellaneous Details
- Tool: The interactive graph was generated using the Google Motion Chart Widget.
- Data: The data presented here was collected by the PingER project, processed by prmout. The same data is available in tabular format. The statistics of Population were acquired from the U.S. Census Bureau, the country to region mapping was obtained by the geographical database maintained by the PingER project, where as the Internet usage statistics were taken from Internet World Stats. Please note that while all the statistics were acquired over several years (i.e. since 1998), the Internet usage statistics were documented in Nov. 2007.
- Loading: The time to load and render the web page is largely determined speed of the link, the file length (about a MByte that is determined by the number of metrics and frequency of data points and the number of metrics) and the speed of the client rendering.
- Metrics: Average RTT (ms), Normalized Throughput (Kbps), Internet Users (#), Internet Penetration (%), Population (#), Minimum RTT (ms), Packet Loss (%), Unreachability (%), Jitter (ms), DOI Index, HDI Index,
