@xps,
An HTML document can only have one html tag and one body tag. To display multiple charts in a page, you can have multiple chart-containers (div in this case) and have just one script-tag where you create both chart1 and chart2 and render them. Please take a look at this tutorial on Rendering Multiple Charts in a Page.
Also please take a look at tutorial on HTML and this stackoverflow thread for more info.
