Request: line chart icon and more data icons in general

[rafgraph]

Hi, I really like this icon set, the design ascetics are on point! It'd be great to have a line chart icon to use with the bar chart and table icons.

Also more data related icons in general would be useful as well. For example icons for: data (to represent raw data not in any form), processing data, scatter plot, bubble chart, pie chart, and area chart. Thanks!
