Can someone please provide a basic walk-through/tutorial of implementing data from a rails application into D3 chart format? (e.g. want to turn the data from my index page into chart format)
I understand there is a way to do this via JSON, but I am not sure how to do it with multiple columns of data.

I have a plot made using Python matplotlib that updates every time new sensor data is acquired. I also have a web GUI using vue. I'd like to incorporate the matplotlib figure into the web GUI and have it update as it does when running it independently. This therefore means not just saving plot and loading it as an image.
Can anyone advise how to achieve this?
In my opinion it's not reasonable way, There are very good visualizing tools powered by javascript, for example chart.js.
you can do your computation with python in back-end and pass data to front-end by API and plot every interactive diagrams you want using javascript.
I have a python/pandas application that does data analysis and outputs reports to csv format. I would like to out an interactive front end UI on top of this application so the user can mix and match data, select parameters for scenario testing, have interactive charts and dashboards displayed on screen instead of csv etc.
I am looking to use Django, but for interactive charts, do I need to learn a javascript library (which one), or will Django be sufficient?
I recommend going to agree with Django (and moving your csv into a database). Out of the box Django 2 brings sqlite which is a file based database that would offer you the ability to swap database files if you wanted. I've found this (https://www.fusioncharts.com/django-charts/) django-charts package that incorporates interactive charts with Django, and seems to have lots of examples.
I am developing a website where I have around 800 data sets. I want to visualize my data using bar charts and pie charts, but I don't want to hard code this for every data set. What technology can I use to dynamically read the data from a json/csv/xml and render the graph? (btw I'm going to use a Python based backend (either Django or Flask))
Js library like d3.js or highcharts can be helpful to solve your problem. You can easily send the data from sever to front-end where these library can gracefully plot the data.
Can anyone help me to implement orientdb visualization graph or neo4j visualization graph as a stand alone library which can be customised with respect to my json format? Actually i want to visualise my data using that kind of visualization graph.Thanks in advance.
My requirement is to generate charts using fusion charts.
I'm supposed to provide data to fusion charts from MongoDB which is a no SQL database.
MongoDB stores data into collections which is in the json format.and fusion charts accepts the data either in json format or in Xml format.
how should i provide the data to the fusion charts?
Currently I have written a java class to read the collection and put it into the .json file and I am passing this json file to the fusion charts(ie. a program written in html embedded with javascript)separately.I am stuck with the issue that how to call a java function from javascript?
Hence is there any other better alternative for this ??
Well, it isn't an easy task. You must make a Java Web Application with a Servlet, REST service or whatever you want. Then you must deploy the application in an application server like Tomcat or JBoss, so your HTML+Javascript application is able to do request to your Java service.
You can't call a standalone Java class from an HTML+Javascript page.
I think you're trying to do something that you don't know anything about... and must read a lot about the subject.
how should i provide the data to the fusion charts?
FusionCharts has specific data formats for different charts. So if you have got the data from your MongoDB you need to parse and create FusionCharts compatible JSON data. So any JSON data wont work.
I hope I am wrong in assuming that, you have already done so. Otherwise you really need to learn a lot about simple things about reading the basics of any library, you intend to work.
