comment Can Mathematica draw networks with nodes having multiple layers?
Draw the rectangle, then at the same location the circles. Later drawings go over earlier ones.

comment In WolframAlpha, how can I make a Scatter Plot without connecting points?
I'm voting to close this question as off-topic because WolframAlpha queries are mentioned in the forum's charter as being off-topic unless they involve calls from within Mathematica.

comment Plot a simple line x=t^3 + c
The 5th example on the Plot documentation page should give you all the information you'd need.

comment incuding graphics
Graphics`Graphics was used in (I believe) version 5 and lower. In the version you have you don't need it. For legends look up the PlotLegends option. BTW The ClearAll without arguments doesn't do anything...

comment Can Mathematica draw networks with nodes having multiple layers?
If the connections are not deterministic, using graphs will be hard. If it's just about drawing you should be able to do this yourself with Graphics and its multitude of graphics primitives. You'll need Circle, Line, Rectangle, FaceForm, EdgeForm, Arrow, BezierCurve/BSplineCurve. Try that, and come back if it doesn't work.

comment Can Mathematica draw networks with nodes having multiple layers?
That's all doable. My question was more about connection logic. Do red and blue always point to purple, and black to black? What kind of nodes are possible? 1, 2, 3 circles in a green box as shown or are there more possibilities? Black and purple always in an oval and blue in a square? Please be specific as it may determine what is possible and how it needs to be specified. Additionally, do you want to use graph algorithms further on or do you simply want a pretty picture?

comment Can Mathematica draw networks with nodes having multiple layers?
Yes, but it will take some hacking with VertexShapeFunction and EdgeShapeFunction and some information encoding in the specification of the nodes. Do you have a full specification of node types and connection rules?

comment DateListPlot: Highs and Lows
That's what I did already. The data given is just an example. Just wanted to point out that you have an implicit and unwarranted assumption in your approach.

comment DateListPlot: Highs and Lows
Does this guarantee that you always pick the first peak if there are ties and data isn't ordered?

comment How to trim the image after rotating?
@Mr.Wizard Posted an answer. Not sure whether the above counts as a "simple mistake" although ImageRotate was listed under "See also" on the Rotate help page.

comment How to trim the image after rotating?
Use ImageRotate instead of Rotate. Rotate works on Graphics primitives and objects and returns a Graphics primitive or objects with head Rotate.

comment Plot contours for 3d histograms
But that contour describes a local density and it does neither relate to the total data count within the contour (original question) nor the probability of finding a member of the data set within the contour (update in comment) which is what you seem to want. If you simply want the density contours from a SmoothDensityHistogram why don't you use that?

Doesn't look like a usable definition either.

comment How to reverse irreversible function in Mathematica?
Some (perhaps it's better to say most) expressions cannot be inverted analytically no matter how smooth they are. You can define a numerical inverse using InverseFunction if all parameters are known.

comment Plot contours for 3d histograms
I don't know but is it really possible to define a single contour that would encompass say 60% of the data points? I'd say there will be a multitude of contours that do that.

comment Using a For-loop to do numerical integration
In the above, ϕ1 equals (1-2 xd)^(2/3) - (1+2 x d) (2/3)? Thee question is still confusing: do you want to increment both over xd and x?
