So Longford-Westmeath results are in, so we can now look at the geographic breakdown of the final votes and seats in the Irish General Election:
Beginning with the most important: who won seats where?
In the next two plots, the size of the pie-chart are proportional to the number of seats being contested (so Dún Laoighaire was adjusted to only have 3 out of 4 seats contested as the Ceann Comhairle is returned automatically). Renua won no seats (so the colour orange is slightly redundant in these legends!)

Dublin: Labour won no seats south of the Liffey; but the Greens won two. Social Democrats won one seat in Dublin; Fine Gael won at least one seat in every Dublin constituency (and two in Dún Laoighaire and Dublin Bay South). Fianna Fáil improved their lot over 2011 when they won a single seat in Dublin – now they have 6 seats in Dublin. PBP-AAA won 5 seats in total in Dublin while Sinn Féin won 7. Independents also won 7 seats in Dublin.

Interesting constituencies include Tipperary: 3 out of 5 seats were won by Independent candidates and Roscommon-Galway where 2 out of 3 seats were won by Independents.
Fine Gael managed to return at least one TD in all of the other constituencies (barring the two with two with a majority of independent seats), with two returned in Wexford, Kilkenny-Carlow, Limerick County, Clare, Galway-West, Mayo, Wicklow, Meath-East and Louth.
Fianna Fáil returned at least one TD in all non-Dublin constituencies, with two in Cork South-Central, Cork North-West, Kilkenny-Carlow, Kildare South, Kildare North, Cavan-Monaghan, Sligo-Leitrim and Mayo.
Sinn Féin won two seats in Louth and one in: Donegal, Sligo-Leitrim, Cavan-Monaghan, Meath West, Offaly, Laois, Wicklow, Kilkenny-Carlow, Limerick City, Kerry, Cork North-Central, Cork South Central, Cork East and Waterford.
