{"version":"1.0","type":"rich","title":"post- rake db:migrate","description":"This visualization shows a sparse matrix of “did not trace” errors generated by a Ruby script after running `rake db:migrate` with an AWS S3 gem. It renders each error message as a thin horizontal band, with the textual message encoded as a dark strip against a light background. The layout uses a stacked row-per-line approach, where the y-axis positions correspond to the order of errors and the x-axis encodes character positions. The code relies on a custom drawing routine that iterates over the text file, using a monospaced font grid to plot individual characters as filled rectangles, creating a compact, scannable log overview.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-10899257?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
