Is your feature request related to a problem? Please describe

We don't deliver a default way of displaying the data from different runs to end-users.

Describe the solution you'd like

Create a simple UI, that retrieves data from the microservice and displays the change in values across a given time period.

[Idrinth]

views needed for the UI:

• view 1: a line graph per project to compare their global performance(user choice of Average or Median) + a bar graph with the error count
• view 2: a line graph per id in a project to compare their performance(user choice of Average or Median) + a bar graph with the error count
• view3: from two selected points for an id in view 2 show a detailed table for comparison + show a line graph of that id compared to the average for that id over the period

specific features needed for the line graphs:

• show standard deviation by either coloring the area or adding a +/- stdev bar to the measurement points
• all lines have to be toggleable
• the default displayed time is 7 days ago until now but should be changeable

https://svelte.dev/ seems to be the best candidate for this specific topic after having a look at a few of the options.
