Supported chart types

• BarChart - bar chart
• PieChart - pie chart
• ScatterPlot - point distribution

Input data format

As an input utility takes following values separated by a space: the chart type (in any case), the name of the data file, in which the values are stored in separate lines in format "name:value" (for ScatterPlot, the name is the x coordinate), and the name of output file. If output file does not exist, it will be created.
