Desktop Tableau 9 Short Project, on (a) and (b) aspects to be met

This is a Desktop Tableau 9 Short Project, on (a) and (b) aspects to be met only. The selected Desktop Tableau 9 developer or programmer got to create and submit a project whereby only 2 features are needed: (a) if values being referred to in dataset is negative, Big circle with Shaded Red color will be shown (for example when GDP growth is -3%), and by contrast if values there are positive, then a Big circle with Shaded Blue color will be shown (for example when GDP growth is +2%). (b) Also, depending on the extent of the negativity/positivity and magnitude of the numbers being referred to, say GDP growth +8% or GDP growth -5%, then some customized text messages will be shown in a Dialog Text message box below them. For example, highly positive means "Rapid growth ...", while highly Negative means "Growth sharply dwindles to negative territory", etc. Allow for several possible scenarios, in the customized text messages inserted into Dialog box, so you may have to use combination of "If..and Else If" statements, to catch the most relevant one of these various possible scenarios. That's all. The underlying dataset thus comprises only a few points and at a given point in time. [Note: because Tableau can be managed by codes.] Simple? I think so. So, to qualify, you have to use your own mockup dataset or dummy dataset to illustrate this. For future use, I will override just this one, if project is subsequently put to use. Pre-requisite requirement: i) The Desktop Tableau 9 developer has to show the afore-mentioned results being achieved successfully on his PC, via Teamviewer Demo to me, before I am certain the selected person can deliver scope of the entire project to me. Sharing ofTeamviewer login credentials to me is thus important as I need to preview results on his computer screen to be assured of his or her capability. ii) Milestone will only be created when the above part, ie part (i) happens to provide certainty that the chosen Tableau 9 developer or programmer has the capability to accomplish and deliver entire project scope to me. Please read the pre-requisite requirement above, before proceeding further. Please read the Pre-requisite requirements above before placing bids. No compromise on the above pre-requisites. No up-sell on services is allowed. Bid price, when project is awarded, must represent the full price of the project. If I am not wrong, this is actually already one of freelancer.com's terms and conditions , but I make this point even more explicit. As this is very simple, expect quick completion and delivery of the project to me.
