5Python-nvd3 is a Python wrapper for NVD3 graph library.
6NVD3 is an attempt to build re-usable charts and chart components
7for d3.js without taking away the power that d3.js gives you.

17 A bullet chart is a variation of a bar graph
18 used to indicate the value of a single variable
19 in relation to a set of qualitative ranges. It is
20 inspired by a dashboard gauge or thermometer chart.
22 Python example:
24 from nvd3.bulletChart import bulletChart
25 chart = bulletChart.bulletChart(name=type, height=100, width=500)
26 title = 'Revenue',
27 subtitle = 'US$, in thousands'
28 ranges = [150, 225, 300]
29 measures = [220, 270]
30 markers = [250]
31 chart.add_serie(
32 title=title,
33 subtitle=subtitle,
34 ranges=ranges,
35 measures=measures,
36 markers=markers)
37 chart.buildhtml()
