Graph - is the program that builds a graph linking points with lines. It loads coordinates of the points from the text file. Data in the file must be in the folowing format: first 4 numbers in the file are bounds of the graph (gx1 gy1 gx2 gy2), the next values are coordinates of the graph points (x1 y1 x2 y2 x3 y3 ... xn yn). Fractional Numbers as points coordinates supported. Use "." or "," sign to separate the integral and fractional parts of numbers, use spaces to separate numbers.
