How to visualise a project with different stages/dates

Hi, 

I got requested to do visualisation of prospects, that have different 8 (9) different stages. 

9th is "Rejection". 

Every time a new stage is introduced, there is a seperate column that gives a date for just that stage: 

I'm wondering how I should visualise this? 

Columns:
Deal Name
Deal Status
8 different date columns 

Not all of the date columns have values, sometimes the deal status jumps a few steps. Then the steps between gets "null" (it's how our CRM is built)

The Orange in the pictures, indicates when a decision has to be made by the business. I want to highlight that in my visualisation.
