+## Project Retirements Graph
+
+The following graph shows the number of Projects retiring for each year
(**NOT** including **Sub-Projects**).
+
+{% assign sorted_years = site.data.years_array | sort: 'year' -%}
+{% assign no_of_years = 20 -%}
+{% assign first = sorted_years | size | minus: no_of_years | at_least: 0 -%}
+{% assign second = first | plus: 1 -%}
+
+{: .note}
+This is currently configured to show the last **{{ no_of_years}} years** of
retirements (easily changed through the `$no_of_years` variable).
+
+```mermaid
+xychart-beta
+ title "Project Retirements by Year"
+ x-axis "Year" [{{ sorted_years[first]['year']}}
+ {%- for year in sorted_years offset: second -%}
+ {{ year['year'] | prepend: ', '}}
+ {%- endfor %}]
+ y-axis "Number of Projects" 0 --> 18
+ bar [{{ sorted_years[first]['p_count']}}
+ {%- for year in sorted_years offset: second -%}
+ {{ year['p_count'] | prepend: ', '}}
+ {%- endfor %}]
+ line [{{ sorted_years[first]['p_count']}}
+ {%- for year in sorted_years offset: second -%}
+ {{ year['p_count'] | prepend: ', '}}
+ {%- endfor %}]
+```
+
+## Project Retirements Timeline
+The following timeline shows Projects retiring for each year (including
Sub-Projects, if any).
+
+{% assign no_of_years = 20 -%}
+{% assign first = sorted_years | size | minus: no_of_years | at_least: 0 -%}
+
+{: .note}
+This is currently configured to show the last **{{ no_of_years}} years** of
retirements (easily changed through the `$no_of_years` variable).
+
+```mermaid
+timeline
+ title History of Project Retirements
+ {% for year in sorted_years offset: first %}
+ {{ year['year'] }}
+ {%- assign sorted_projects = year['projects'] | sort: 'retirement_date'
-%}
+ {%- for project in sorted_projects -%}
+ {{ project['project_name'] | prepend: ' : '}}
+ {%- endfor -%}
+ {% endfor %}
