Infographics are computer-generated artwork that attractively displays simple tables and charts. They can be things like a bar graph about how many flowers are sold and they use flowers stacked to represent bars.
You could also do something for that where you have a giant flower pot with a pie chart showing different types of flowers that are sold.
This can be useful because readers like visuals that are attractive. Also, plain graphs are kind of boring and dressing them up with images makes them more interesting.
Creating them is relatively simple and can be done on Microsoft Office, Power Point, and other software applications. However, if you are considering publishing it commercially and distributing it to the media you may want to consider using a graphic design artist or other commercial illustrators.
This is my example of an infographic above. I created it in Microsoft Office, and it was relatively simple.
