What type of chart is this? and ideas on programs, developers and models.

[Johnny Lee]

I am creating a program that will allow users to plot their data points on a chart so that they can visualize their data.  The chart will be round and will be divided into sections like a pizza pie. Each section will indicated a different variable of the subject. It will be similar to a star/radar/spider chart in that it will have a series of variables with the value ranked on the axis scale.

However, some difference that I need:

• I do NOT want the connecting lines between the data points, just the data points with a title
  
• the closer that it is to the center, the higher the value which is usually in the reverse order. I imagine that would be easy to configure.
• I would like the data points to fit anywhere in the "pie section", not along the axis. in reality, the pie section really would be a series of axis, all of the same variable within a section.  this is because we may have several data points of the same value and the same variable (just a different data point).

Example of typical radar chart with data point on Axis Line

I would like for my chart to have multiple data points that can be placed anywhere in the chart so you can have 2 or 3 data-points with the same value and within the same variable (in this case, the variable can be broad like "health" and each data-point can be items like different diagnosis).  see example:

 

• ideally, I would like to be able to drag the datapoint around the chart, thus changing its rank and which variable it pertains to. 
• users can change the number of sections/variables as well as the titles of the variable
• Ideally, would like to be able to zoom into the center if there are too many data points near the center and you need to see each data-point better. 
• ideally, would love to be able to double click on data point to go to window where you annotate each one with description, date, source, etc.

So

• is there a name for this kind of chart?
• is it possible to customize a radar chart framework to get to do this?
• any good programs or services that can help me build this part of the online program?
• anyone know of developers/services who can do this (bootstrap project=not a lot of money)?

thanks so much

NOTE: variables are NOT in a series and are not related or connected. the chart may have 1000 data points or just one.
