Anything else the reviewers should know about the changes here

Missing from the spec

• ability to support raw values (only normalised available). This requires some work in the pipeline.
• ability to show logarithmic vertical scale. Easy, but requires guidance on what to do with zeros.
• ability to manage the x-axis labels
