Create a graph series object for the storage of multiple graphs across a sequential or temporal one-dimensional array.

## Arguments

- graph
A graph object to add to the new graph series object.

- series_name
An optional name to ascribe to the series.

- series_type
Either a

`sequential`

type (the default) or a`temporal`

type (which requires date-time strings and time zone codes to be supplied).

## Examples

```
# Create three graphs
graph_1 <-
create_graph() %>%
add_path(n = 4)
graph_2 <-
create_graph() %>%
add_cycle(n = 5)
graph_3 <-
create_graph() %>%
add_star(n = 6)
# Create an empty graph series
# and add the graphs
series <-
create_graph_series() %>%
add_graph_to_graph_series(
graph = graph_1) %>%
add_graph_to_graph_series(
graph = graph_2) %>%
add_graph_to_graph_series(
graph = graph_3)
# Count the number of graphs
# in the graph series
series %>%
count_graphs_in_graph_series()
#> [1] 3
```
