Graphs and Plots in Rails

Update? Not necessarily (and certainly not just for this!), I still
have clients on 1.1.6 and none of my clients are on Rails 2.x yet.

Try these:

<a href="<%= GoogleChart.pie(10,20,40,30).to_url %>">link to chart</a> <img src="<%= GoogleChart.pie(10,20,40,30).to_url %>" alt="Google pie
chart" />

which should be what you'd get from: <%= link_to 'link to chart', GoogleChart.pie(10,20,40,30).to_url %> <%= image_tag GoogleChart.pie(10,20,40,30).to_url, :alt => "Google pie
chart" %>

You could even add the 200x200 size, but that's a frivolous detail
until it works.

The URL works when I paste it into a browser so it should be working.
