CSV files and using Bokeh

Community Support

Hello guys,

I am taking an introductory information visualization course.I am not a computer science student but I have some beginner level programming skills and we are require to do programming to this course.I am thinking about using bokeh.I am going to visualize the data of plane crashes since 1950.I only have a cvs file and I don’t know much about json files.So my Question is Can I just use panda and add my csv file and then use bokeh? or does it have to be a json file?I have tried to convert my cvs file to a Json file but since it changes the formatting and it is no more a table I don’t know how to access my columns .

Hi Niloofar,

`import pandas``

``from bokeh.plotting import figure, output_file, show``

``

``# pandas``

``df = pandas.read_csv('test.csv')``

``# read in name, x , y``

``# print df.x, df,y``

``

``# bokeh``

``plot =  figure()``

``plot.scatter(x=df.x, y=df.y)``

``

``output_file('test.html')``

``show(plot)

  Hope this helps.

  Raphael
