File:Distribution of Number of Species per Genus in all plant genera.png
Summary
| Description |
English: Distribution of species across various genera. Each point represents a bin of a certain range of species count.
Data from World Flora Online Plant List June 2023. https://zenodo.org/record/8079052 To reproduce, download the `classification.csv` file, then run ```python import pandas as pd import matplotlib.pyplot as plt import numpy as np
with open('classification.csv', 'r', encoding='latin1') as file: df = pd.read_csv(file, delimiter='\t')
genus_counts = df['genus'].value_counts()
counts, bin_edges = np.histogram(np.log10(genus_counts), bins=100)
bin_centers = (bin_edges[:-1] + bin_edges[1:]) / 2.
fig, ax = plt.subplots() ax.scatter(10**bin_centers, counts, s=5)
ax.set_yscale('log') ax.set_xscale('log')
ax.set_xlabel('Number of Species in Genus') ax.set_ylabel('Number of Genera') ax.set_title('Distribution of Number of Species per Genus') plt.grid() plt.show() ``` |
