❶ Click the download button at the top right side of the infographic.
❷ Click the High quality tab at the top of the page.
❸ Enable the transparent background option in the right sidebar.
❹ Click the blue Download (PNG) button in the right sidebar to download your chart in PNG format.
Once you've downloaded the image, upload it from your computer anywhere into your Prezi presentation.

Simply click Insert -> Charts and choose a chart type that matches your data the best to start visualizing.
