*New in v2.0, the tool now generates SVG files.*

This is a tool to generate simple Gantt charts. Here's some sample output:

![Gantt Chart Output](example/project.svg)

The focus of the tool is the generation of the chart from existing data and not the calculation of project dependencies.

Install with `cargo install gantt_chart`.  Run with `gantt-chart`.  If you have [resvg](https://crates.io/crates/resvg) installed, you can generate a PNG bitmap with:

```sh

resvg example/project.svg example/project.png --background '#ffffff'`

```

It has the following features:

- Takes input date in a simple [JSON5](https://json5.org/) format

- Groups tasks by resource

- Schedules a tasks for each resource as soon as the previous one is complete

- Allows the creation of zero length project milestones

- Automatically generates resources colors using a [Golden Ratio](https://martin.ankerl.com/2009/12/09/how-to-create-random-colors-programmatically/) algorithm

- Customizable column widths

- SVG allows easy scaled conversion to other formats

- Tasks can be shown as done or not-done

- You can add a dotted line to mark the current or other date

- Can generate a table of resources

- Takes into account weekends and extends task durations as needed so the start & end to falls on a weekday

You can use the tool to quickly generate high level project timelines.  For full blown Gantt functionality, I recommend a tool like [OmniPlan](https://www.omnigroup.com/omniplan).
