Here’s a quick and easy (and free!) way to see realtime stats on the number of people visiting your website or blog: http://whos.amung.us
They don’t describe themselves as a page counter, but as a people counter.
http://whos.amung.us/learnmore shows how to add a counter that shows live visitors
These other two widgets work with the data generated:
http://maps.amung.us/ displays world map of where our visitors are coming from
http://graphs.amung.us/ does all kinds of graphs in varying sizes and designs.
