# software tool for accurate visualization of algebraic curves

First of all, I apologize since this is not strictly speaking a "mathematical" question but I could not find a better place for it.

For a work presentation I need a tool for accurate visualization of implicit algebraic curves in 2D. I tried ImplicitPlot function from Maple but for some complicated curves the results are not satisfiable. Also, it is not very convenient to zoom at certain locations along the curve.

I appreciate if someone can recommend me a good software tool for curve visualization thanks

PS. One of the equations I need to visualize is the following: (1-(1/5000000000000000)*x-(1/5000000000000000)*y-2*x^2+(1/5000000000000000)*x^3-(1/10000000000)*y^6+x^4-(1/10000000000000000)*y^5-(1/10000000000000000)*x^5+y^4-(1/10000000000)*x^6+(1/5000000000000000)*y^3-2*y^2+(1/1666666666666666)*x*y^2+(1/1666666666666666)*x^2*y+10*y^2*x^2-4*x*y+(5999999/1000000)*x*y^3+(5999999/1000000)*x^3*y+6*y^4*x^4+(3999999/1000000)*y^5*x^3+(499999/500000)*y^6*x^2-(3999999/500000)*y^4*x^2-(999999/500000)*y^5*x-(1/3333334444444814)*y^4*x-(1/1000000)*y^7*x+(3999999/1000000)*x^5*y^3-12*x^3*y^3-(1/2500000625000156)*x^2*y^3+(499999/500000)*y^2*x^6-(3999999/500000)*y^2*x^4-(1/2500000625000156)*y^2*x^3-(999999/500000)*x^5*y-(1/3333334444444814)*x^4*y-(1/1000000)*x^7*y)=0

Have you tried SAGE? –  Derek Allums Aug 18 '12 at 15:01
Even better: check out GrafEq. –  Ｊ. Ｍ. Aug 18 '12 at 15:20
You can improve Maple's output if you use numpoints=20000, for example. –  Sigur Aug 18 '12 at 15:24
thanks for suggestions. I need to vizualise some "degenerate" algebraic curve which should look like two crossing lines ending abruptly. I just tried GrafEq on this equation and it hangs somewhere with Graph (82%). For implicit plot I tried up to numpoints=100000 and resolution=600 but it still does not produce any adequate image –  asm Aug 18 '12 at 15:51
Yes, and it's also freely available on the Internet: www.sagemath.org. –  Derek Allums Aug 18 '12 at 17:30
