What is it? Info.gram
What does it do? Creates easy to read infographics, charts and maps
How does it work? Sign up, and a step-by-step process will take you through creating a graphic.
It would help to be familiar with how to use a spreadsheet. One is available to fill in, but you can also import various spreadsheets.
You can choose among different types of charts, including treemaps (which show proportion clearly), bubble charts (which plot like charts but also show relativity in a cool way) or population charts.
You can add media, including photos and video, have multiple people collaborate on a graphic, and keep track of analytics.
There is a limited amount you can do with a chart in the free portion of this website. But, for feature purposes, this might be enough.
You can embed the chart into your web page, or share it through social media.
Have fun with it.
