hello

I want to make some graphs/charts with bars.

1) How can I do this easily? by specifying the x and y axons and by specifying the values? also it would be nice to be able to specify the SD values too

then, I need to make more interesting the graph/chart, so I came across this:

2) how can I achieve the exact same in inkscape?

3) or do you have another nice idea for great looking and eye catching graphs/charts with bars?

thanks

Arrange them like so:


Add a few gradients:
