I'm just starting to take a look at Bokeh for data visualization and am wondering the advantage/disadvantage to using Figure.vbar() vs Bar() if someone could clarify.

Bokeh can be used to plot multiple lines on a graph. Plotting multiple lines on a graph can be done using the multi_line() method of the plotting module.
You can display images on Bokeh plots using the image() , image_rgba() , and image_url() glyph methods. You can use hovering tooltips with image glyphs to let the user see the values of each pixel.
Bokeh is a Python library for creating interactive visualizations for modern web browsers. It helps you build beautiful graphics, ranging from simple plots to complex dashboards with streaming datasets. With Bokeh, you can create JavaScript-powered visualizations without writing any JavaScript yourself.
bar is from the high level Charts interface. It gives you quick, easy access to bar charts with limited control.
vbar is from the mid level Plotting interface and gives you more control over the layout of your bar chart. Alternatives to vbar would be rect and quad, both from the Plotting interface. They give a few distinctive options for bar shape, location, etc.
baris much easier if you don't need to do anything fancy. If you decide you want more control over your plot (likeHoverTooletc) you will have to instantiate aFigureand use one of it's methods.

I use both, depending on my needs.
