You can use JavaScript to lazy-load the graph, as long as there is no legal
requirement that the graph be universally available, since it will just not
load in the absence of a scripted client. Note that Google will skip it as
well, if that matters to you.
Refactor your graph code so you can request the graph from its own URL, then
use an Ajax request to load it asynchronously into the page.
Using Prototype, put the following in a script block below the div where your
graph will appear:
new Ajax.Updater('div_where_the_graph_goes', 'url/to/the/graph');
For extra credit, add an inline placeholder div within your
div_where_the_graph_goes element, with its background set to a loading spinner
GIF. This will be replaced when the Updater finishes.
