Plotly (1) is a great graphics library for producing dynamic plots. It also has an R interface. A simple example of a Gantt chart with R/plotly is shown in (2). Here is a more complicated version: a job shop problem with 10 jobs and 10 stages (3).
The colors correspond to the machine used in each stage. Machines are numbered 0…9.
These are screen dumps. I have not figured out yet how to use R/plotly dynamic plots in blogger.
