I've uploaded spreadsheets that automatically generate XML code for charts in SVG format.

Summary: You simply paste or enter your data into the spreadsheet, and specify image dimensions, number of grid lines, data ranges, font sizes, etc. The spreadsheets instantly and automatically generate a column of XML code. You simply copy and paste that code into a text editor and save as an ".svg" file. The spreadsheets produce lean SVG code, and should save you time in creating SVG charts. Though my original spreadsheets are written in Microsoft Excel, I've received reports that they also work if read into other spreadsheet programs.

Feedback and suggestions on my talk page are welcome. RCraig09 (talk) 23:41, 19 February 2021 (UTC)
