Try this:
d = RandomReal[{0, 1}, {78, 20003}];
ListDensityPlot[d, PerformanceGoal -> "Speed"]
ListPlot3D[d, PerformanceGoal -> "Speed"]
Mathematica deals with large data sets by downsampling, using the
MaxPlotPoints option. PerformanceGoal->"Speed", will use a very simple
plotting code to give a draft representation of the data (no mesh
lines, no RegionFunction, etc.).
This also works, although it may take a little bit longer, around 20
sec on my mac book pro with 2Gig RAM:
ListDensityPlot[d, PerformanceGoal -> "Speed",
MaxPlotPoints -> Infinity]
or even:
ListPlot3D[d, PerformanceGoal -> "Speed", MaxPlotPoints -> Infinity]
Mathematica is a very good tool to visualize large data sets.
