Q. d3.js setup in android - javascript

I want to visualized data using collapsible tree provided by d3.js. I'm following the tutorial http://www.appstoremarketresearch.com/articles/d3-js-pie-chart-android-webview/.
Unfortunately, i'm not sure how to start from scratch (installing d3.js) and how to run it in android apps. any reliable references? thanks.

The answer is the post you linked itself, see section Make a Pie Chart in an Android Fragment and WebView:
To make D3.js charts in an Android application, first download the
D3.js source from the D3.js home page.
Then
In your app project path, create a directory for JavaScript assets: Android-D3jsPieChart/assets/js
Copy the minified d3.min.js source file from your download into Android-D3jsPieChart/assets/js
Create a directory for HTML assets: Android-D3jsPieChart/assets/html
Create file Android-D3jsPieChart/assets/html/piechart.html. Copy this code into the new file:
D3.js Pie Chart
The code above allows you to use d3 library from assets in your webview. After you have done these setups, you can proceed to any normal d3.js tutorials and use them in your webview, for JavaScript files (.js), you can continue to put them in assets folder.

How to import html page as pdf in nodejs

I have an html page which contains graph created with Amcharts
and I need to generate pdf of my html page. Amcharts have provided
this link for exporting html in javascript my question is there is any way to export a page from server-side i.e nodejs.
There is no such tutorial in a given site and so far I have tried phantomjs plugin but it didn't help.
Amcharts has a knowledgebase article showing how to do this. If you prefer an alternative you can try pdfmake and build up the pdf with the png's yourself.
Once you have the pdf you can serve the file over an endpoint on node pretty easily, eg using express.

reveal.js working/bootstrap example

I found reveal.js but I couldn't find a simple working example.
I found this but they are either too complex or cannot find the source.
Does anyone have a simple example?
The reveal.js repository on GitHub is in itself a demo for a simple presentation.
You can simply fork the project on GitHub, clone the fork to your local file system and edit the index.html file in the root directory to get started with your presentation.
I myself have created several presentations this way, most recently this one: https://github.com/pahund/devugees-prez-oct2017
If you create your presentation on a special Git branch named gh-pages, you can even view it online without having to deploy it to a server, for example: https://pahund.github.io/devugees-prez-oct2017/
If you don't want to install all the components (around npm) needed to use reveal.js, you can still use a docker image like agiled-de/reveal.js-docker
This images makes it easy to use reveal.js with docker. It supports the use of the following plugins:
MathJax Enables you to write LaTeX formulas in your presentations
reveal.js-menu Adds a menu to test themes, transitions and jump to slides
Chalkbord Write on your slides or on a chalkboard
Reveal.js-Title-Footer Adds a footer that will stay on every slide
Charts To create charts within your presentation
vis.js To create graphs in your presentation
And it has a demo_presentation/index.md included.

Chart is not working on offline

I need a multi screen chart on html5 in offline. I used Google Chart and that was perfect, but It's could not work offline for their terms of service but I need Chart in offline.
Please watch the attached file.
Please watch this attached image . I need that type chart in offline.
So tell me how do I fix that problem.
You can do it by downloading required JS file locally and use them to generate chart for example, for D3.js all you need to do is download d3.js file and use code shown in link to generate chart.
Most of the chart library will work if you download relative js file and use those downloaded js file path instead using CDNs.

D3JS with Kibana

Is it possible to host a D3.js control inside kibana
So for example if I click a cell in a row in kibana it should run a D3.js Background .Will it require a change in the Kibana source code ?
Apparently, it is possible: though integration within an existing dashboard may not be trivial. From the linked article:
As I understand, you want to access your custom script dashboard. If
so, keep your script file (.js) directly under app/dashboards and
access that http://localhost/kibana/#/dashboard/script/.js
