This is interactive pollen diagram where the horizontal axis represents time or depth. The vertical axis shows taxa abundance.

• The zoom widget (top row) can be used to view the data in more detail. Click, hold and drag across the widget to select the portion of time/depth to be shown in the diagram.
• Vertical exaggeration can be controlled (left). Setting it to one, or less, will render it invisible.
• Toggle taxa on/off using the taxa selection widget (left).
