How to get data from google directions API?

What are the typical sources for data visualizations of web data?

  • Like usage for: Quora, Google, Youtube, Facebook, Twitter. I'm remotely aware of something that some of these sites have APIs, that can be used for extracting data but are not exclusively for that purpose (?). If not, it seems that you could write a data crawler to draw a certain subset of data. Do these crawlers tend to ignore the robots.txt file but try to spread out their requests to be considerate (and not get blocked?) And if the site has an API, do they allow you to make unlimited requests for your data needs? Generally quite confused. Any detailed explanation of some subset v. welcome, and links to websites/tutorials too!

  • Answer:

    I've had a number of conversations in our Thought Leaders in http://www.sramanamitra.com/big-data/ series of interviews on the http://1mby1m.com blog all of which point to the fact that data visualization is currently an open area without sufficiently good solutions. Nonetheless, here is a good starting point for your investigation: http://www.sramanamitra.com/2013/01/14/thought-leaders-in-big-data-interview-with-stew-langille-ceo-of-visual-ly-part-1/

It sounds like you need a way to get data from websites to make Visualizations with. Here is a video showing you EXACTLY how its done 'step by step' by Jewel Lowree from Tableau using http://import.io (were I work) : There is no need to worry about the technical aspects like request rates etc.. is already done for you. When A website does have an API,  I'd encourage you to use if possible. The more API's there are on the web the better! They will have documentation about limits and things like that, which will be different for each API
