Big Data Mining, automate data using google trends

Google trends gives the data of google searches for particular keywords. I want to write a program that will be automatically fetch this data after every 15days (It gives daily data) and show it on our website in the form of map... So that people seeing the website should get an idea as to what is trend for searching particular keyword (In our case keywords are Malaria and Dengue). In google trends website it already gives map.. But it is shown as a point data for Pune.. But I want a it to be shown as a choropleth map.. That is boundary of Pune should show colour shade... I dont know if I am clear.. Or else I can explain you better on phone...!!!! To do that we may have to link this data to whole of Pune region and then give different shades of colours to specify if the searches are more or less.. I have attached a file which will give schema of what is expected... To write a program google trends.
