This function generates edge information from a given triangular object, including the coordinates of the vertices and the from-to relationships between the vertices.
Value
A tibble that contains the edge information, including the from-to relationships and the corresponding x and y coordinates.
Examples
r2 <- diff(range(s_curve_noise_umap$UMAP2))/diff(range(s_curve_noise_umap$UMAP1))

r2 = r2)

df_bin_centroids <- extract_hexbin_centroids(centroids_df = all_centroids_df,
counts_df = counts_df) |>
dplyr::filter(drop_empty == FALSE)
tr1_object <- tri_bin_centroids(hex_df = df_bin_centroids, x = "c_x", y = "c_y")
