• Interactive Charts – Emprise creates dynamic charts that are fully interactive. Users can zoom in and out, scroll, and use features such as mouse tracking, hints and key tracking and events.
• Automatic – Emprise automatically scales the axes to the data, ensuring that each chart is laid out in the most space efficient manner.

• Import – Data can be imported on-the-fly from XML formatted files.

jQuery Google Charts:

jQuery Google Charts is a free javascript plugin that creates simple charts using basic source code. It has limited features, which are centred mainly on the creation of the following charts:

• Barcharts – You can customise colours, dimensions, axis labels, spacing, background and more.
• Stacked Barcharts - horizontal or vertical
• Line Charts - There are a variety of options here, including filled line charts, the style of the line and sparklines.
• Pie Charts
• 3D Pie Charts

You can access JQuery Google Charts here. It appears that all data must be entered manually, which will of course be a series drawback to any business or organisation that has a large amount of data to be charted.
