Create this example
Create a console project, add the ChartForgeX package, and replace Program.cs with this source. Run it to write SVG, PNG and HTML with the default system fonts.
For the same typography as the gallery, download the gallery-font recipe and copy the gallery’s fonts directory beside your program.
