[jQuery] animating the size of a div

[jQuery] animating the size of a div


I am creating graphs with CSS. What I would like to do is animate the
graph... ie, have the div slowly grow from 0 to 75%.
Here is the css I use:
.barbg{
height:17px;
border:1px solid #999;
width:120px;
float:right;
}
.color{
height:17px;
background:url(bgraph_03.gif) repeat-x top;
}
Here is the HTML I use:
<div class="barbg">
<div class="color" style="width: 75%;"></div>
</div>
