Data-driven javascript visualization
€250-750 EUR
Paguhet në dorëzim
I need a Javascript/JQuery piece of code that receives a data stream and plots the data in an svg or canvas.
Each data stream record contains the positional coordinates of 20+ elements plus attributes that determine what, for each element, must be visualized.
Further details will be provided to the selected freelancer.
Further details: the visualization in Javascript must be done in real time and must be synchronized with a video that will be displayed close to it.
The visualization will be paused/resumed based on the user's action on the video controls.
Ideally each data record will have to be processed and visualized in < 40ms. (1 record = 1 video frame = 25 frames/sec). For starters we could accept a processing and visualization time of < 200ms. (5 frames/sec)
Your code will be part of a web page. It will be invoked to process a json array of objects every 40 milliseconds. Each json object in the array will contain the spatial coordinates (X, Y) relative to a plane plus some numerical values which will be used to determine what to plot. For each json array (in real-time) your code will have to draw each object (as a simple geometrical figure like a circle or square or a number) in its position on the plane. Additionally for each object the code will draw other visual information, like for instance a trail like in the video, or a circle around each object whose radius will be determined by a number. At the beginning, before start processing the data stream, the code will draw a rectangle, representing a soccer field.
Actually the data processing loop must be able to visualize the data of one json array as fast as possible. Ideally in less than 40 milliseconds, but the timing might be a bit more relaxed (120 msec.) depending on the type of visualization. The point is: the code I am seeking will do in Javascript what today is done in a video like the one attached
