Topola – online genealogy visualization

Topola is a Typescript/Javascript library for embedding genealogy tree visualizations on web pags. The library uses D3 under the hood for rendering SVG images.

Available chart types:

• Ancestors
• Descendants
• Hourglass chart (both ancestors and descendants)
• Relatives chart (descendants, ancestors and descendants of ancestors), based on the All-in-one report in GenealogyJ
• Fancy chart, inspired by https://imgur.com/a/T02Kc7X
