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 discrete bar chart or bar graph is a chart with rectangular bars with 

18 lengths proportional to the values that they represent.

23 from nvd3 import discreteBarChart 

24 chart = discreteBarChart(name='discreteBarChart', height=400, width=400) 

25 

26 xdata = ["A", "B", "C", "D", "E", "F"] 

27 ydata = [3, 4, 0, -3, 5, 7]

42 

43 chart.margin({top: 30, right: 60, bottom: 20, left: 60}); 

44 

45 var datum = data_discreteBarChart; 

46 chart.yAxis 

47 .tickFormat(d3.format(',.0f')); 

48 chart.tooltipContent(function(key, y, e, graph) { 

49 var x = String(graph.point.x);

61 .attr('height', 400) 

62 .call(chart);

67 You can also disable the tooltips by passing ``tooltips=False`` when 

68 creating the bar chart.
