Regarding your query, please check the official doc:

Please check the attributes and its explanations:
cluster_min_size.
- Optional, defaults to 2. Minimum number of markers that can get wrapped into a cluster.
cluster_click_zoom.
Optional, defaults to on , can be on or off. This attribute sets whether clicking on a cluster should zoom it. By design, it sets the fitbounds value of the map based on the markers contained in that cluster. Sometimes, this attribute needs to be used together with the cluster_max_zoom attribute to dissolve a cluster when markers are too close.
cluster_max_zoom.
- Optional, defaults to empty. When cluster is set to on , this attribute sets the minimum zoom level that dissolves clusters into individual markers again.
cluster_grid_size.
- Optional. Defaults to 60 (pixels). When cluster is set to on, this attribute sets the minimum distance in pixels between two markers to join them into the same cluster.
cluster.
- Optional, defaults to off . Can be on or off . When set to on, markers close enough based on some rules will be rendered as a cluster.
The default cluster_min_size is 2 and if you use 1 there is no point of making cluster if there is only 1 marker. You use cluster_grid_size='1' but its in pixel default to 60 pixels.
