I know it’s an old trick but I learnt it only recently. As of now, I use Mermaid for Gantt but Excel version takes may be five minutes but it is clean enough to use. First, let me post the Mermaid Gantt. Code on the left and the image on the right - I did this using obsidian. Another cool trick when using it is by using CDN. Just build a standard XML and change the content inside that <div class=”mermaid”> tag.
