added a simple bar plot function
world = ct.fetchWorld()
area = world.getArea('US')
ct.deltaPlot(world, "World Deaths Per Day", '/mnt/c/dropbox/workspace/covid-19-tools/tmp/bar_plot_world.png', 'DEATHS', v_thresh = 500, yscale = 'linear', usedates = True)area = world.getArea('US').getArea('Virginia')
ct.deltaPlot(area, "VA Deaths Per Day (after reaching 10)", '/mnt/c/dropbox/workspace/covid-19-tools/tmp/bar_plot_va.png', 'DEATHS', v_thresh = 10, yscale = 'linear', usedates = True, smooth = True)
