Planted Area and Production of Selected Vegetables in Malaysia, 2009-2014
In this entry, I will explain about the Viz that tells the story about the planted area and production of selected vegetables in Malaysia from 2009 until 2014. This Viz has been created by using a dataset from Malaysia’s Department of Agriculture (DOA), which has been provided in the www.data.gov.my
. But first, I will go through what’s this all about. Selected Vegetables
The selected vegetables that have been chosen to be recorded by the DOA are, bitter gourd, brinjal, cabbage, carrot cauliflower, chillies, chines kale, cili padi, cucumber, French bean, kangkung, lady’s finger, lettuce, long bean, petola, pumpkin, radish, sawi, spinach, spring onion, sweet shoot and tomato. All this vegetables have its own categories. You may go through the Viz and interact with it. About the Viz
Planted Area and Selected Vegetables in Malaysia-viz
This Viz basically tells about the planted area and the production of the selected vegetables. In this story, I have 4 chapters describing about the data given. In the first story, it tells about the average yield of the vegetables throughout the years. In the dashboard, you can click on the list of the vegetables and it will only shows the chosen vegetables.
For chapter 2, I’ve started to compare the planted area and the harvested area. Each of the vegetables were specified on how large the planted area needed. But not all vegetables in those area will grow. The harvested area shows the vegetables that succeed to grow. The green colour shows planted area provided for the vegetables, while the pale blue colour shows the harvested area of the vegetables. The non-harvested area graph shows the area that does not produce any vegetables. You can shows the vegetable that you want to view and know about. Just have a click at the filters.
Well, the most interesting part when analyse this data is, we get to know the difference between the farm price and the wholesale price. Tableau helps to visualise both prices in the same axis. The filters at the right side, help us to interact with the visualisation. You can take a look at the Viz. For the bar graph, it shows the percentage difference between the wholesale price and farm price. You can use the calculated field features for the custom formula.
As for the last chapter, it visualise the production of vegetables based on the harvested area. Besides that, I also made a comparison between 2 years. Choose 2 years that you want to compare, and have a look whether the production is increasing tremendously or vice versa. Production of vegetables are based on the harvested area, so you can look the circled graph below it, and you can guess why the production is increasing or decreasing.
