Two new experimental features

A few weeks ago two new features were released. The first is a world map view of the country page and the second shows how the network size changes over time.

World Map

The world map shows two different data sets. Red circles represent where hubs say they are located. The size of the circle indicates how many hubs are reported to be at that location. Green circles represent how many hubs are in that country based on their IP address and mapping it to a country using Maxmind’s GeoIP. The location of the green circle is either drawn roughly in the center of the country it represents or at the country’s capital. The country location data was collected from

Network size changes

The network size page shows graphically how the network size is changing. Each data point shows how many hubs or leaves joined or departed the network from the previous network measurement. So for example if one data point reads +200 hubs then 200 hubs joined the network between that time and the last network measurement.

This also is the debut of pChart usage on the crawler website. It makes creating beautiful and useful graphs easy. I look forward to using it more in the future.
