Looking for suggestions/validations and advice on how to approach the following problem
I want to build a real time charting application. Something very similar to stock ticker chart,except there is more data on the screen.I receive the data from web sockets calculate/operate on the data and update the charts.New data arrives with a gap of one secs.Few things to consider here-the incoming data can be huge(millions of array) and therefore the operations on the data might be time intensive.Also this app would be only used by me. The goal is to make the chart informative, with whatever technology works .Here is how I am approaching the problem
- Browser based solution- I use d3.js for rendering the charts. The calculation and operation happens on the web worker(this would keep the rendering thread unblocked). In such a scenario ,will the browser be able to handle such high intensive calculations? Would I run into performance issues?
- Use nodejs based solution – To make the calculation out of the browser, move the calculation logic on nodejs server.The server receives the data from websocket and calculates/operates on the data and sends the binding json to the client(browser) which then renders the chart. Question- Would it be prudent to send this huge json to client every second(even tough the app is running on localhost), then the client de-serializes it and renders it.
- Appjs or node-webkit- Make desktop application with node.I can still take advantage of d3.js, as webkit allows rendering html/css. Not sure how this would help exactly.
- Desktop Apps based charting- Move out of browser and html rendering. Use c++/QT to write the operation logic(I have already written the logic of calculation and for a million data points the numbers showed around 500ms , this option looks good to me). Here the calculation is winner but the rendering sucks, no data binding, updating each element on the chart is time intensive.
If anyone can give his/her opinion on what approaches would be better from the above or any other different way to handle this ,would be really helpful
