    data[genres[index]][0] += duration
    data[genres[index]][1] += 1

for genre in data:
    data[genre][0] = data[genre][0] / data[genre][1]

labels = list(data.keys())
values = [v[0] for v in data.values()]

plt.scatter(labels, values)
plt.xticks(rotation='vertical', fontsize=8)
plt.title("Average Playtime By Genre")
plt.ylabel("Average Playtime (seconds)")
plt.xlabel("Genre")
plt.show()
