TRAINERS FOR COURSE


Details

To interpret your data and draw insights, you need to be able to visualise it. Python, one of the most popular and powerful coding languages around, has impressive libraries and resources for displaying your data. You'll be able to take your data and use it to tell insightful stories with compelling visualisations to convince stakeholders and build trust.

In this course you will learn to:

  • Create data visualisations
  • Use various graph types
  • Apply skills to real world scenarios
  • Improve data accessibility and understandability
  • Create robust summaries

Schedule Dates and Booking

There are currently no scheduled dates.

Please note that this course needs a minimum of 6 delegates to schedule a course. You can choose to be added to the waiting list by clicking the button below and we will contact you when we have enough delegates interested. Should we not get enough delegates, we will refund or credit your paid booking.

Add me to the waiting list

Should you need this course urgently, the following options are available:

  1. Pay for 6 delegates (whether you have them or not) and we will schedule the course as soon as possible.
  2. If you have fewer delegates and cannot pay for 6, we can negotiate a shortened course where some of the time will be spent in blended learning - watching videos and doing tutorials and exercises with some contact time with the trainer. We would want to discuss what your core needs are so that we cover those aspects. You need to have paid for 3 delegates at least.
