I'm trying to start a project regarding a stock trading tool. I would like to extract data from an existing stock chart online. However, I thought it would be easy as parsing HTML code, but I noticed that most of them are made of javascript which I am not familiar with.
I'll be using python 3.4 for this project.
Any starting ideas would be deeply appreciated!
Cheers!

I am using Django to make a dashboard to show sensor data.
I am using chart.js for that
I am retrieving sensor data of two days or less only.
The problem is that how can I divide my graph for it.I think it might be possible using python time library or Django or something like that if so kindly suggest me some way to do it.
I think that if java script can help us that will be great too.
I just want data parsing based on time to plot and view it nicely.
I want to implement a xhtml Page in my Java EE project, which will show data from a db. The chart I had an eye one was NVD3 charts, which is based on java script.
The implementation I had in mind was like this:
User can fill in textfields with a "from-date" and a "to-date" to set the date-range where data from the database should be collected. The collected data will then be marshalled into JSON format and the chart created based on the data. Here I somehow have to get the marshalled data from Java to the JS function.
I guess I could this get to work, I am quite a fan of the NVD3 charts but somehow this mixing of JavaEE with JSF and javascript seems bad practice to me.
I wanted to know if this is kind of a bad idea to do and what you would advise me to do here?
Thanks in advance
I'm using java spring for backend of my website. I need to add some auto generating graphs to it. But I'm not sure for what I should look for. Should I use a Javascript library or can I do it in java as a backend function? This is my first time using this functionality.
P.S.
I have to deal with a often updating database to fetch data for those graphs.
Check this answer, I would suggest to go with option 2 and use a javascript library like highcharts.

Does India have a .geoJSON file? I want to make data visualization using d3.js for the states, cities and hence need the GEOJSON File representing India. Where should I start from or what should be my approach?
Also
Mike's Tutorial doesn't help much for a Windows guy dealing with conversion of geographical data for the first time.
Please help.
Thanks,

here you can get all the countries geojson files..
check it out..
and there are lots of tutorials available to do the task you requested...

http://techslides.com/d3-world-maps-tooltips-zooming-and-queue/
apart from these you need to search and find tutorial to learn much more concepts...
These two are the basic tutorials to start off with maps in d3.
Programming noobie here. I'm working on a website where users fill out a form and based on their input a given value from a big excel sheet is displayed on the page. I know JS, jQuery, HTML/CSS, and Python but I haven't learned how to use any framework like Django yet. I'm wondering how I can most easily read values from the xls doc. It looks like xlrd is a good bet. I'm doing this project on a tight deadline though so I'm not sure I have time to learn a framework like Django and it seems like overkill for something as simple as this. Can I use xlrd for the website without learning a framework? And more broadly, what's the simplest way to implement this solution (i.e. read values from an XLS doc onto a web page)?
Django is a big framework, consider using Flask microframework (it shouldn't take your more than 4 hours to get the basics and put together simple application).
The easiest approach would be to go with Microsoft technology stack - you can expose quite easily Excel sheet as Web Service, so the web page can read it data as JSON or XML.
