前言:好有錢嘅租客?

之前睇過一個連登 post 討論九龍站上蓋值唔值得租,見到其中一個 comment 咁樣寫:

有錢嘅話仲買乜樓呀,直接租豪宅,每一兩年就搬屋,住吓唔同區之餘又有新鮮感咪仲好

「租租」呢個詞彙本身係連登房屋台用黎諷刺睇淡樓市,一直租樓等樓市跌先買樓嘅人。但租樓嘅人,又唔代表佢一定無錢。古語有云「貧窮限制自己想像」,或者有錢人嘅興趣係租樓都唔定。

常理推斷,高 …

What is a waffle chart? What is a waffle chart on map? When should this type of map be used? This article serves as a gentle introduction to waffle chart and waffle grid map, using a dataset of convenience stores in Hong Kong.


人口密集嘅城市自然需要密集嘅日常社區設施。喺街道入面隨處可見,唔同種類嘅日常設施到底有幾密?呢篇文章搵咗幾種日常設施嘅數據,分析吓佢地有幾密。

為咗寫上一篇文,我收集咗全香港 7–11 位置嘅數據。喺分析堆數據嗰陣,我放咗 7–11 嘅位置地圖上 Instagram story,俾其他人估吓堆點代表咩設施。以下喺部分回答:

M 記/銀行/公廁

當我個 friend 答「公廁」嗰陣,我專登上食環署個網睇吓全香港有幾多間公廁。而結果係有 809 間¹。

7-Eleven and Circle K are two major convenience store chains in Hong Kong. Where could you find more store in one chain compared to the other? And what is the magnitude of differences?

總有一間喺左近

我搵唔返(歡迎讀做「我唔想做literature review」)呢句slogan嘅出處,但佢都証明咗香港嘅7–11開到成行成市。

咁到底7仔開得有幾密?呢個係第一個問題。

同樣係便利店,全香港有接近成千間7–11,但OK就只係得300幾間,足足差成700間。咁就帶出第二個問題:會唔會有某啲地方係OK多過7–11?(劇透:有)。如果有嘅話,咁OK會多過佢幾多間?(劇透:3間左右)

數據來源

兩間集團嘅官網都有每間便利店分店嘅位置,所以只要做少少data scraping就可以砌到一個便利店dataset。Data scraping嘅話,Python人就用Beautiful Soup;我寫開R,所以用rvest

免責聲明:set data 1. 無validate過;2. 唔係最新version;3. 可能visualise嗰陣copy漏咗幾行。有錯有漏唔係意外,係我懶。
