The Website I liked the most is Visual.ly.  This website contains a lot of useful information on many different subjects and its code of ethics is to provide accurate information (See below for a complete description of their code of ethics).  Through Visual.ly I was able to find clear illustrations in different topics such as:

1.     USA Presidents – social studies facts useful for president’s day and other

2.     Tips on English grammar usage – Language Arts

3.     Languages – Studying abroad

4.     Plenty of science illustrations

5.     Valentine’s Day – Facts on how the tradition started

6.     Pregnancy Week by Week – any age health class

7.     Cost of Ipad in classrooms instead of textbooks

8.     My favorite “Strange Christmas traditions around the world” http://visual.ly/christmas-madness-strange-christmas-traditions-around-world

Con’s not much information on mathematics.

Great information on psychology but very little on sociology.

Ethics

As an organization that both practices and recognizes quality data-journalism, Visual.ly subscribes to the code of ethics of the Society of Professional Journalists and agrees to abide by all of its principles.

We also agree to the following principles to support data analysis and visualization:

Data will be accurate and verifiable - Visual.ly will not "lie with statistics."

Proper Sourcing & Attribution - Visual.ly will always give credit where due and will do its own reporting.

Best Practices in Visual Representation - Visual.ly will not exploit idiosyncrasies of the human visual system to exaggerate or misrepresent data.

Most succinctly stated, Visual.ly's policy is one that encompasses accuracy, honesty, and transparency.

While Visual.ly will do our best to promote these standards, the policy applies only to the visualizations we create ourselves and those we feature as staff picks, not to those uploaded by members of the community.
