Haiku Deck's web application is a great tool for designing visually-appealing slideshows. The latest update to the Haiku Deck web app includes support for charts and graphs. Now in your Haiku Deck slides you can create bar graphs, pie charts, and stat charts. You can adjust the values in bar graphs by clicking and dragging each column. Pie charts are made by typing percentages. Stat charts are simply captioned columns of statistics.
The latest update to Haiku Deck also includes support for multiline slides. This is a feature that I'm not terribly excited about because it allows students to write more text on their slides than they could before. One of my favorite features of Haiku Deck has always been the text limitations which forced students to choose their words carefully.
