The "chart.apis" server that you were using was deprecated for many years, and has finally been turned off.
The "visualization-api" is an interactive charts library that works quite differently. Part of that library was a wrapper around the "image charts" which use the "chart.apis" server. See https://developers.google.com/chart and https://developers.google.com/chart/image/docs/gallery/chart_gall for details.
