Hello, Peity!

+

That's pretty amazing. It's so simple and looks so nice... and it is easy to use, can be used + just anywhere. I like the design and charts... how could I not fall in love in + peity?

+

Pie charts!

+ 1/5 + 226/360 + 0.52/1.561 +

Line charts!

+ 1,1,1,6,2,2,7,3,5,15 + 5,3,2,-1,-3,-2,2,3,5,2 + 0,-3,-6,-4,-5,-4,-7,-3,-5,-2 +

Bar charts!

+ 5,3,9,6,5,9,7,3,5,2 + 5,3,2,-1,-3,-2,2,3,5,2 + 0,-3,-6,-4,-5,-4,-7,-3,-5,-2 +

What next?

+

Actually, I don't know. Probably I'll just use it anywhere possible. + So simple and lovely <3
