Good day friends I write for the following problem or lack of knowledge that I have, I must develop a web application that does the following using svg, js, bd and json I explain: it will be an application where we will use temperature sensors where these readings temperature will be sent to a database and we will have a panel where restrictions will be placed which is the maximum temperature an example 40 degrees = maximum temperature, ok and to have this we will make a map type a mine where in svg and when the sensor detects a maximum temperature this in the map svg in a section is changed to red color this warning that that section the temperature is very high and they must dislodge down I show you an example.
I hope I can explain. good and this should be done with svg, js, and json in php but I do not know how to start and I hope someone can help me since I can not find any information on the Internet, I have an example that happened to me but I do not give an idea I leave the link to download example link
In this example the lots that are already sold are marked in red, the sections in orange and those available in gray.
I look forward to your contributions.
