Gantt Charts are a commonly used tool in project management, so it's no surprise that Airtable recently added these as an option as a Block.
As is true with most blocks, you must first tell Airtable in which table and view your underlying data resides. From there, you have a few options in setting up your Gantt Chart – namely dates, dependency fields, grouping, and colors.
For dates, the block works as you might intuitively expect. You can move the records in your Gantt Chart and have the underlying data automatically updated to reflect those changes.
Regarding the dependency feature, Airtable has allowed you to label one or more other tasks as either dependent or reliant. This is done using a 'link field' within your data set.
Lastly, the color feature allows you to take more control over the visualization of your Gantt Chart.
